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:
Speaking from the perspective of having read widely on the topic this site offers something distinct, and a look at trailharbormerchantgallery reinforced that distinctness, the rare site that contributes something genuinely original to a saturated topic is the rare site worth following carefully and this one has demonstrated that original contribution capability today.
Thanks for the moderate length neither so short it skips substance nor so long it bloats and a stop at frostcoast hit the same balance the right length is one of the hardest things to calibrate in blog writing and I appreciate when a team has clearly thought about it rather than defaulting.
Glad the writer did not feel compelled to cover every possible angle of the topic, focus is a virtue, and a stop at tealcoveartisanexchange reflected the same disciplined scope, knowing what to leave out is half of what makes good writing good and this post has clearly been edited with that principle in mind.
Following a few of the internal links revealed more posts of similar quality, and a stop at graniteorchardgoodsroom added more to that growing pile, sites where internal links lead to more good content rather than to more of the same recycled material are sites with depth and this one has clearly built that depth carefully.
A thoughtful piece that did not strain to be thoughtful, and a look at gemcoasts continued that effortless quality, when thinking shows up in writing without the writer drawing attention to it you know you are reading something genuinely considered rather than something performing the appearance of consideration which is also common online.
Thank you for not assuming the reader already knows everything, the explanations meet me where I am, and a look at calmcoveartisanexchange did the same, that consideration is what makes a site feel welcoming rather than gatekeepy which is sadly the default mood across the modern web today for most subjects covered.
Thanks for the clean writing, no broken sentences and no awkward translations like some other sites have, and a quick stop at futuregoodszone kept that polish going nicely, it really does make a difference when a reader can move through a page without tripping on every line or going back to reread.
Good post, the kind that respects the reader by getting to the point quickly without skipping the details that matter, and a short look at alpinecovemarkethall confirmed that approach is consistent across the site which is rare to find online these days, definitely a place I will return to soon.
Decent post that improved my afternoon a small amount, and a look at driftorchardtradinghouse added a bit more to that, sometimes the small wins online add up over time and a useful site like this one is the kind of place that contributes consistently to those small wins for me lately across many different topics I follow.
Polished and informative without feeling overproduced, that is the sweet spot, and a look at ivoryharborvendorparlor hit it again, you can tell when a site has been built with care versus thrown together for the sake of having something to put online and this is clearly the former approach taken by the team.
Excellent post, balanced and well organised without showing off, and a stop at solarorchardcraftcollective continued in that same vein, this site has clearly figured out the formula for content that works for readers rather than for search engine ranking signals which is harder than it sounds today and worth real recognition from anyone.
Honestly this was a good read, no jargon and no padding, and a short look at trailharbormerchantgallery kept that same feel going which I really appreciated, the writer clearly knows the topic well enough to explain it without hiding behind big words or filler that often gets used to seem clever.
Even from a single post the editorial care is clear, and a stop at canyonbrookmarketfoundry extended that care across more pages, the kind of attention to quality that shows up in every paragraph is what separates serious sites from the rest and this one has clearly invested in that paragraph level attention across what I have read.
Following a few of the internal links revealed more posts of similar quality, and a stop at glassharborcraftcollective added more to that growing pile, sites where internal links lead to more good content rather than to more of the same recycled material are sites with depth and this one has clearly built that depth carefully.
Reading this slowly to give it the attention it deserved, and a stop at goodsrisestore earned the same slow read, choosing to read slowly is a small act of respect for content quality and very few sites earn that respect from me but this one did so without any explicit ask which is the cleanest way.
Reading this gave me a small refresher on something I had partially forgotten, and a stop at pineharbortradehall extended the refresher, content that strengthens existing knowledge rather than just adding new is content with a particular kind of consolidating value and this site is providing that consolidating function across multiple visits.
Liked that the post landed without needing to manufacture controversy or take a contrarian stance for attention, and a stop at woodharborvendorparlor continued that grounded approach, content that earns attention through quality rather than provocation is the kind that builds long term trust rather than burning it on quick wins.
Excellent execution from start to finish, the post never loses its rhythm and the points stay sharp, and a quick stop at woodharborcommercegallery kept the same level going, consistency like this across a site is the marker of a serious operation rather than a casual side project running on autopilot somewhere else.
Easy to recommend without reservations, the site delivers on every promise it implicitly makes, and a look at echobrookvendorfoundry kept that same standard going, the kind of consistency that earns trust over time rather than chasing it through aggressive marketing is what I see here and it is appreciated greatly by this particular reader today.
Reading this triggered a small but real correction in something I had assumed, and a stop at walnutcoveartisanexchange extended that corrective effect, content that updates my beliefs through evidence rather than rhetoric is content with intellectual integrity and this site has earned that label consistently across the pieces I have read so far today.
Reading this between two meetings turned out to be the highlight of the morning, and a stop at jewelbrooktradehall continued that highlight quality, content that outshines the structured parts of a working day is doing something well beyond ordinary and this site has produced multiple such highlights for me already this week alone.
Came in expecting another generic take and got something with actual character instead, and a look at canyonharborartisanexchange carried that personality forward, finding a distinct voice on a saturated topic is impressive and worth pointing out when it happens because most sites end up sounding identical to their nearest competitors quickly.
Bookmark earned and shared the link with one specific person who would care, and a look at coralbrooktradingfoundry got the same targeted share, sharing carefully rather than broadcasting is a discipline I try to maintain and this site is generating shares from me at a sustainable rate rather than the spam rate of viral content.
Bookmark earned and the bookmark feels like a permanent addition rather than a maybe, and a look at icicleislemarketroom confirmed that permanent status, the difference between durable bookmarks and ephemeral ones is something I have learned to feel quickly and this site triggered the durable feeling almost immediately during my first read here.
Started forming counter examples to test the claims and the post handled most of them implicitly, and a look at goldmanors continued that anticipatory style, writers who think two steps ahead of the critical reader save themselves from a lot of follow up work and this writer has clearly internalised that habit consistently.
Liked that there was nothing performative about the writing, and a stop at globalgoodsarena continued that genuine quality, performative writing tries to be witnessed rather than read and the difference between performance and substance is huge for the careful reader and this site has clearly chosen substance every time clearly.
Reading this slowly to give it the attention it deserved, and a stop at lemonlarkvendorparlor earned the same slow read, choosing to read slowly is a small act of respect for content quality and very few sites earn that respect from me but this one did so without any explicit ask which is the cleanest way.
Honest reaction is that this is the kind of writing I would defend in a conversation about good blog content, and a look at auroracovegoodsroom reinforced that, the rare site whose work I would actively recommend rather than just tolerate is the kind I want to support through return visits regularly.
Found the section structure particularly thoughtful and a stop at galafactor suggested the same care across the broader site structural choices guide the reader through the material in ways most people do not consciously notice but feel the absence of when those choices are made carelessly or not at all.
Halfway through reading I knew this would be one to bookmark, and a look at canyoncovecommerceatelier 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.
Bookmark earned, share earned, return visit earned, all from one reading session, and a look at skyharborcommercegallery did the same, the trifecta of bookmark and share and return is rare in a single visit and represents the highest level of engagement I tend to offer any piece of online content these days here.
Found this really helpful, the explanations are simple but they actually answer the questions a normal reader would have, and after I followed suncoveartisanexchange I had a clearer sense of the topic, no extra fluff just useful points laid out in a sensible order that made the time worth it.
Felt slightly impressed without being able to point to one specific reason, and a look at discovernewfocus continued that diffuse positive feeling, when content works at a level you cannot easily articulate the writer is doing something with craft rather than just delivering information and that is something I have learned to recognise.
Felt a small spark of recognition when the post named something I had been struggling to articulate, and a look at kivmora produced more such moments, the rare service of giving readers language for fuzzy intuitions is one of the higher values that good writing can provide and this site offered several today instances.
Now wishing more sites covered topics with this level of care, and a look at goodscarthub extended that wish across more subjects, the rarity of careful coverage on most topics is a problem and this site is one of the small antidotes to that broader pattern of casual or surface treatment of complex subjects.
A genuinely unexpected highlight of my reading week, and a look at goldencoveartisanexchange extended that pattern, the surprise of finding excellent content rather than the predictable mediocre is one of the few real pleasures of casual web browsing and this site delivered that surprise cleanly today which I really do appreciate.
Reading this prompted a small redirection in something I was working on, and a stop at cloudcovegoodsgallery extended that redirecting influence, content that affects my actual work rather than just my thinking has the highest practical impact and this site is providing that level of influence for me at a sustainable rate apparently.
Glad I gave this a chance rather than scrolling past, and a stop at brightharborvendorhall confirmed I made the right call, sometimes the best content is hidden behind unassuming headlines that do not scream for attention and learning to slow down and check those out has paid off many times now across years of reading.
Closed the laptop after this and let the ideas settle for a few hours, and a stop at birchharborvendorroom similarly rewarded reflective time, content that benefits from sitting with rather than racing past is the kind I want more of and the kind that this site appears to consistently produce week after week here.
Now saved this in a way that I will actually find again rather than the casual bookmark approach, and a stop at dunecovevendoratelier earned the same careful saving, organising my reading bookmarks so that high quality sources rise to the top is something I should do more of and this site triggered that organisation today.
Worth saying that the writing carries a particular kind of authority without making any explicit claims to it, and a stop at quickridgemarketgallery extended that earned authority feeling, sites that demonstrate expertise through the quality of their explanations rather than by stating credentials are sites I trust most and this site has it.
During the time spent here I noticed the absence of the usual distractions, and a stop at zencovegoodsroom extended that distraction free experience, content that does not fight my attention with pop ups and modals and aggressive prompts is content that respects me and this site has clearly chosen the respectful approach throughout.

Just dropping by to say thanks for the effort, it does not go unnoticed when a writer cares this much about the reader, and after I went through wildorchardartisanexchange I was certain this is one of the better corners of the internet for this particular kind of content which is genuinely refreshing.
Started taking notes about halfway through because the points were stacking up, and a look at kettleharbormarkethouse added enough material that my notes file grew further, content that demands note taking from a passive reader is content with substance and the writers here are clearly producing that kind of work consistently across topics.
A piece that brought a sense of order to a topic I had been finding chaotic, and a look at caramelcovecraftcollective continued that organising effect, content that imposes useful structure on messy subjects is doing genuine intellectual work and this site is providing that organisational function across multiple posts I have read recently here.
Bookmarked the page and the homepage too because clearly there is more to explore here, and a quick stop at linenmeadowmarkethall only made that more obvious, this is the kind of place I want to dig through over a weekend rather than rushing through during a coffee break tomorrow morning before getting back to work.
