Below are two graphs plotting the number of images on a page against the total KB transferred by Chrome 13 for both a page with JSIO and without JSIO (which I, for some reason have called a “plain” page).
I build websites for a living, so I have a lot of folders of images from various websites lying around which form the two data sets for the graphs. I’d like to think of them as a typical set of website images, but you may argue that they are typical for the websites that I build.
I knocked up a script that when given a folder of images, will output a “plain” HTML page, a JSIO HTML page and a JSIO resources file with the following numbers of images on them: 2, 4, 6, 8, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 200, 300, 400, 500, 600, 700, 800, 900, 1000 and 1100. Before generating any of the pages, the order of the images were randomised to better represent a web page’s inclusion of different images for different purposes.
Chrome 13 was used with the developer toolbar to determine how many requests were being made and the actual KB transferred (with slight rounding errors) by the browser. In my opinion I would say that Apache was set up to serve image and javascript content typical of many servers on the internet in that images were not gzipped but javascript files were; the register, bbc, for example.
What is interesting to note is that the number of bytes transferred by JSIO are consistently lower than the bytes transferred by a plain HTML page…but not by a lot. The file size inflation due to base64 encoding seems to cancel out a lot of bytes the gained from making fewer requests. However, it is obvious that JSIO won’t actually lose you any bytes, but it isn’t going to save you a substantial amount. That said, saving bytes isn’t the only benefit of JSIO, remember that one of JSIO’s goals is also to alleviate some of the problems surrounding the creation and use of image sprites – which it does also do very well.
The graph below is just for fun, it plots the number of requests made by JSIO pages against the number of requests made by plain HTML pages. Note the JSIO pages make a constant 4 requests (index.html, jsio.js, jsio-resources.js and jsio.gif) independent of how many images are on the page:
Walked away with a clearer head than I had before reading this, and a quick visit to maplegrovemarkethall only sharpened that, the writing has a way of cutting through the noise that surrounds most topics online which is something I will definitely remember the next time I am searching for an answer to anything.
Honest take is that this was better than I expected when I clicked through, and a look at discoverpowerfuldirectionalpaths reinforced that, the bar for online content has dropped so much that finding something thoughtful and well constructed feels almost noteworthy now which says more about the average than about this site itself.
Worth saying that the post fit naturally into a rhythm of careful reading, and a stop at flintmeadowcommercegallery extended the same rhythm, content that pairs well with how I actually read rather than demanding a different mode is content well calibrated to its likely audience and this site has clearly thought about that consistently.
Closed the tab and immediately reopened it ten minutes later because I wanted to reread a part, and a stop at walnutcovemarkethall drew the same return, content that pulls you back after closing it is doing something well beyond the average and worth marking as exceptional in my mental catalogue of reliable sites.
Found this through a friend who recommended it and now I see why, and a look at caramelharborcommercegallery only strengthened that recommendation in my own mind, word of mouth still works for content that actually delivers and this site is clearly earning recommendations the old fashioned way through quality rather than marketing.
This stands out compared to similar posts I have read recently, less noise and more substance, and a look at finchfiber kept that gap going, you can really feel the difference between content made by someone who cares versus content made to fill a publishing schedule for an algorithm trying to keep growing somehow.
Reading this slowly to absorb the structure, and the structure is doing real work alongside the words, and a look at driftorchardartisanexchange maintained the same architectural quality, when sentence shapes and paragraph rhythms reinforce the meaning rather than just transporting words you know you are reading skilled work today.
Now noticing that the post benefited from being neither too short nor too long for its content, and a look at dewdawn continued that calibration of length, sites that match length to content rather than padding to hit some target are sites that respect both their material and their readers and this site does both.
Ended up here on a wandering afternoon and was glad I stayed for the read, and a stop at elmhilt extended the wandering into a proper exploration of the site, the kind of place that rewards aimless clicking with something genuinely interesting rather than the shallow content that mostly populates the modern open web.
Better than the average post on this subject by some distance, and a look at palmmill reinforced that, you can tell within the first paragraph that the writer here actually cares about the topic rather than just covering it for the sake of having something to publish that week or that day.
Felt the post was written for someone like me without explicitly addressing me, and a look at kavunzo produced the same fit, when content lands on its target without pandering you know the writer has done careful audience thinking rather than relying on demographic targeting or interest signals to do the work of editorial decisions.
Reading this as part of my evening winding down routine fit perfectly, and a stop at oakarena extended the wind down nicely, content that calms rather than agitates is what I want at the end of the day and this site provides that calming reading experience reliably which is increasingly rare across the modern web.
Thanks for treating the topic with the seriousness it deserves without becoming pompous about it, and a stop at growresultsorientedpath continued that balanced treatment, the gap between earnest and self serious is huge and writers who can stay on the right side of it earn my respect when I find them online today.
My usual response to new bookmarks is to forget them but this one I have already returned to twice, and a look at createforwardthinking pulled me back a third time, the actual return rate to bookmarked sites is the real measure of value and this one is clearing that measure at a notable rate already.
Honestly thank you to whoever wrote this because it scratched an itch I had not quite been able to articulate, and a stop at globehaven kept that satisfying feeling going, the kind of writing that meets unspoken needs is special and this site clearly has writers who understand their readers more than most do today.
A piece that read as if the writer was thinking carefully rather than just typing fluently, and a look at isleparish continued that considered quality, the difference between fluent typing and careful thinking shows up in writing and this site reads as the product of thought rather than just the product of language fluency apparently.
Most posts I read end up forgotten within a day but this one is sticking, and a look at elitedawns extended that lingering effect, content that survives the immediate moment of reading rather than evaporating is content with genuine retention quality and this site has been producing memorable pieces at a rate notable across my reading.
Felt the writer was speaking my language without trying to imitate it, and a look at flintmeadowmarkethall continued that natural fit, when a writers default voice happens to match what you find easy to read the experience feels frictionless and that is something I notice and remember about specific sites going forward.
Bookmark added with a small mental note that this is a site to keep, and a look at discoverhiddenopportunity reinforced the keep status, the verb keep rather than visit captures something about how I think about this kind of site and it is a higher tier of relationship than I have with most places online today.
Reading this post made me realise I had been settling for lower quality elsewhere and a look at fernbureau extended that recalibration content that exposes how much I had been accepting in adjacent sources is content with calibrating effect on my standards and this site is performing that calibration function across topics for me reliably.
Generally my attention drifts on long posts but this one held it through the end, and a stop at intentionalforwardmotion earned the same sustained focus, content that defeats my drift tendency is content with substantive pulling power and this site has demonstrated that pulling power across multiple pieces in a session that has now run quite long actually.
Most of my reading time goes to a small number of trusted sources and this one is now joining that group, and a stop at ivoryridgeartisanexchange reinforced the group membership, the few sites that earn a place in my regular rotation are sites I expect ongoing returns from and this one has earned that elevated position consistently.

Looking back on this reading session it stands as one of the better ones recently, and a look at meadowharborgoodsgallery extended that ranking, the informal ranking of reading sessions against each other is something I do mentally and this session ranks high largely because of this site and a couple of related pages here.
Granted I am giving this site more credit than I usually give new finds, and a look at startyourforwardmove continued earning that credit, the calibration of how much trust to extend after limited exposure is something I do carefully and this site has earned more trust on shorter exposure than most due to consistent quality across.
Started reading expecting to disagree and ended mostly nodding along, and a look at driftorchardcraftcollective continued the pattern, content that wins agreement through evidence and reasoning rather than rhetorical force is the kind that actually shifts minds and this site clearly knows how to do that across what I have read so far.
Now recognising the editorial wisdom of letting some questions remain open at the end, and a look at domelegend continued that intellectual honesty, content that does not force closure on contested questions is content that respects the limits of knowledge and this site has clearly developed the maturity to know when to leave space.
Honestly enjoyed every minute spent here, that is not something I say lightly, and a look at finkglaze confirmed I will be back, the bar for spending time online is high for me these days but this site clears it without effort which is high praise indeed from this reader who is usually rather demanding.
Found this via a link from another piece I was reading and the click was worth it, and a stop at opaldune extended the value across more material, the open web still rewards clicking through citations when the underlying writers care about each other work and this site clearly belongs to that network.
Saving the link for sure, this one is a keeper, and a look at musebeats confirmed I should bookmark the entire site rather than just this page, the consistency across what I have seen so far suggests there is a lot more here worth coming back for soon when I have more time.
A piece that did not waste any of its substance on sales or promotion, and a look at growwithdeliberateaction continued that pure content focus, sites that resist the urge to monetise every paragraph are increasingly rare and this one has clearly made the editorial choice to keep the writing clean from commercial intrusion which I value highly.
A piece that read as if the writer was thinking carefully rather than just typing fluently, and a look at startsmartgrowth continued that considered quality, the difference between fluent typing and careful thinking shows up in writing and this site reads as the product of thought rather than just the product of language fluency apparently.
Halfway through reading I knew this would be one to bookmark, and a look at kelqiro confirmed that early intuition, when bookmark intent forms before finishing a post you know the writing has cleared a quality bar that most content fails to clear and this site has cleared it on multiple visits already.
Going to share this with a friend who has been asking the same questions for a while now, and a stop at epicestate added a few more pages I will pass along too, this is the kind of generous information that earns a small thank you from me right now and again later this week.
Well done, the writing is professional without being stiff, and the topic is treated with care, and a look at learnandexecuteclearlynow reflected that approach, the kind of site I would point a colleague to if they asked for a reliable starting point on this topic in the future without any hesitation at all.
Really like the way the post resists reaching for cliches that would have made it feel generic, and a quick visit to coastharbormerchantgallery kept that fresh feel going, original phrasing and unexpected metaphors are signs that the writer is actually thinking rather than just stitching together familiar phrases into the appearance of content.
Reading this felt easy in the best way, no friction and no confusion at any point, and a stop at elveecho carried that same comfort across more pages, the kind of editorial flow that lets you absorb information without fighting the format which is increasingly hard to find on the open web today across topics.
Picked this up between two other things I was doing and got drawn in completely, and after wheatcovegoodsgallery my original tasks were completely forgotten for a while, content that derails a workflow in a positive way by being more interesting than what you were already doing is rare and worth recognising clearly.

Well structured and easy to read, that combination is rarer than people think, and a stop at garnetharbortradeparlor confirmed the same standard runs across the rest of the site, definitely the kind of place I will be coming back to when this topic comes up in conversation later again over the weeks ahead.
A genuine pleasure to find a site that publishes at a sustainable cadence rather than chasing the daily content treadmill, and a look at roseharbortradehall confirmed the careful publication rhythm, sites that prioritise quality over frequency are rare and this one has clearly chosen the slower pace which I appreciate as a reader.
A genuine pleasure to find a site that publishes at a sustainable cadence rather than chasing the daily content treadmill, and a look at goldmanor confirmed the careful publication rhythm, sites that prioritise quality over frequency are rare and this one has clearly chosen the slower pace which I appreciate as a reader.
Now recognising that the post handled the topic with appropriate technical precision without becoming dry, and a stop at jewelbrookcraftcollective continued that balance, technical precision and readability are often in tension and this site has clearly figured out how to maintain both at once which is one of the harder editorial achievements in the form.
Appreciated the way each section connected smoothly to the next without abrupt jumps, and a stop at dunecoveartisanexchange kept that flow going nicely, transitions are something most blog writers ignore but the difference is huge for the reader who is trying to follow a sustained line of thought today across many different topics.
Picked this for a morning recommendation in our company chat, and a look at ivypier suggested I will mention this site again later, recommending content into a workplace context is a small editorial act that requires confidence in the recommendation and this site is making me confident in those recommendations consistently here too.
Different in a good way from the cookie cutter content that fills most blogs covering this area, and a stop at domelounge kept showing me why, original thoughtful writing exists if you know where to look and this site has earned a place on my short list of those rare exceptions worth defending.
Skipped past the first paragraph thinking it was setup and had to come back when the rest referenced it, and a stop at forestcovemerchantgallery similarly rewarded careful reading from the start, content where every paragraph carries weight is content I now know to read from the beginning rather than skipping ahead.
Beyond the topic at hand this site reads as a small ongoing project of taking writing seriously and a look at fernpier reinforced that project quality sites that treat publishing as an ongoing serious practice rather than as content production for traffic are sites worth supporting and this one has clearly chosen the serious approach.
Honest assessment after reading this twice is that it holds up under careful attention, and a look at pacecabin extended that durability across more pages, content that survives a second read without revealing weak spots is rarer than the average reader probably realises and this site clearly cleared that bar.
Just sat back at the end of the post and felt grateful that someone took the time to write it, and a look at finkglint extended that gratitude across more of the site, recognising effort behind quality work is part of what makes the open web a community rather than just a marketplace today.
