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:
More original than the recycled takes I keep finding on the topic elsewhere, and a quick look at sleekgain confirmed it, the kind of site that has its own voice rather than echoing whatever is trending which makes it stand out as a refreshing change from the usual rotation of generic content I see daily.

Now organising my browser bookmarks to give this site easier access, and a look at duostem earned the same organisational priority, the small acts of digital housekeeping I do for sites I expect to use often are themselves a measure of trust and this site has triggered the trust based housekeeping behaviour from me clearly.
Found a small mental shift after reading this, the framing here is just a bit different from the standard takes online, and a look at zapflux extended that fresh perspective across more material, the rare site whose voice actually changes how you think about something rather than just confirming existing beliefs.
Came away with a small but real shift in perspective on the topic, and a stop at kilozen pushed that shift a bit further, the kind of subtle reframing that good writing does to a reader without making a big deal of it is something I always appreciate when it happens which is sadly not that often.
That is the proper blog for anybody who desires to search out out about this topic. You realize a lot its almost exhausting to argue with you (not that I truly would need?HaHa). You definitely put a new spin on a subject thats been written about for years. Great stuff, simply great!
Appreciate the work that went into laying this out so clearly every section earns its place without filler and a look at rapidshelf confirmed the same care definitely the kind of place that deserves a return visit when the topic comes up again later in the future or for any related question.
This stands out compared to similar posts I have read recently, less noise and more substance, and a look at rustroad 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.
Liked the way the post got out of its own way, and a stop at logicarc extended that invisible craft, the best writing you barely notice while reading because it is doing its work without drawing attention to itself and this site has clearly mastered that disappearing act across the pieces I have read.
Different in a good way from the cookie cutter content that fills most blogs covering this area, and a stop at crystalpetalcollective 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.
The way the post stayed on topic throughout without going on tangents was really refreshing, and a look at amploom kept that focused approach going, discipline like this in writing is rare and worth recognising because most writers cannot resist wandering off into related subjects that dilute their main point and confuse readers along the way.
Reading the writers other posts after this one suggests the quality is consistent rather than peak, and a stop at velvetshorecollective confirmed the consistent quality reading, sites that hold the same level across many pieces rather than peaking on a few are sites with sustainable editorial discipline and this one has clearly developed that.

Here is my blog: top 10 leukste weddenschappen – Arthur -
Felt energised after reading rather than drained, which is unusual for online content these days, and a look at volttray continued that good feeling, content that leaves you better than it found you is rare and worth bookmarking when you stumble across it for the first time today or any other day really.
Quietly enthusiastic about this site after the past few hours of reading, and a stop at fluxvibe extended that enthusiasm, the calibration of enthusiasm to evidence is something I try to maintain and this site has earned a calibrated quiet enthusiasm rather than the loud excitement that usually fades within a day or two of finding something.
Just want to recognise that someone clearly cared about how this turned out, and a look at urbanfernmarket confirmed that care extends across the broader site, you can feel the difference between content shipped to hit a deadline and content released because the writer was actually proud of the result for once.
Thanks for not padding this with the usual filler intros and outros that every other blog seems to require, and a quick visit to zingtrace continued that lean approach across more posts, content stripped of waste is content that respects you and I will always come back to that kind of approach.
Really thankful for posts that respect a readers time this one does and a quick look at glowforgeessentials was the same no need to scroll through endless intros just to get to the actual content that approach alone is enough reason to come back here regularly for the kind of writing offered.
Probably the best thing I have read on this topic in the past month, and a stop at cloudforgegoods extended that ranking, the casual ranking of recent reading is informal but real and this site has been winning those rankings for me on this topic specifically over the last several weeks of regular reading sessions.
Reading this felt easy in the best way, no friction and no confusion at any point, and a stop at sleekhold 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.
Reading this gave me a small mental break from the heavier reading I had been doing, and a stop at fastgoodsarena extended that lighter feel, content that provides relief without becoming trivial is harder to produce than people realise and this site has clearly figured out how to be light without being shallow at all.
Really like that the writer trusts the reader to follow simple logic without restating every previous point, and a stop at linkcast kept that respect going, treating an audience as capable adults rather than as people who need constant hand holding makes a noticeable difference in the reading experience for me.
Reading this in a relaxed evening setting was a small pleasure, and a stop at savvyshopstation extended the pleasant evening reading, content that fits the tone of relaxed time without becoming forgettable is what I look for in evening reading and this site has the right tone for that particular slot in my daily reading routine.
Now saved this in a way that I will actually find again rather than the casual bookmark approach and a stop at royalshelf 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.
Reading this gave me confidence to make a decision I had been putting off, and a stop at beamreach reinforced that confidence, content that translates into action in my own life rather than just informing it is content with the highest practical value and this site is generating that action level utility for me lately.
Halfway through reading I knew this would be one to bookmark, and a look at duotile 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.
Started smiling at one paragraph because the writing was just nice, and a look at premiumcartcorner produced a couple more such moments, prose that produces small spontaneous reactions in the reader is doing more than just transferring information and the writers here are clearly hitting that level fairly consistently throughout pieces.
Started reading skeptically because the headline seemed overconfident, and the post earned the headline by the end, and a look at rustwin continued that pattern of earning its claims, sites that can back up their headlines without overpromising are rare and this one has clearly developed editorial calibration on that front consistently.
Came in for one specific question and got answers to three I had not even thought to ask, and a look at lushfind extended that bonus value pattern, the kind of resource that anticipates reader needs rather than just answering the literal question asked is the gold standard and this site reaches it.
Felt like I was reading something written by someone who actually thinks about the topic rather than reciting it, and a look at crystalpinegoods reinforced that impression, the difference between recited content and considered content is huge and this site clearly belongs to the latter category which I appreciate as a careful reader looking for substance.
Thank you for keeping the writing honest and the points easy to verify against your own experience, and a stop at glamtower reflected the same approach, no exaggeration just steady useful content that I can take with me into my own work without second guessing every sentence I happen to read here.
Now setting up a small reminder to revisit the site on a slow day, and a stop at simplebuycorner confirmed the reminder was a good idea, planning return visits is a small organisational act that signals trust in ongoing quality and this site has earned that planned return through consistent performance across the pieces I have read so far.
Now thinking I want more sites built on this kind of editorial foundation, and a stop at urbanlatticehub extended that wish into a broader hope, sites built on substance and care rather than on metrics and growth are the kind of sites I want to see more of and this one is a small example worth supporting.
A particular kind of restraint shows up in the writing, and a look at vortexarc maintained the same restraint across pages, knowing what not to say is just as important as knowing what to say and this site has clearly developed strong instincts on both sides of that editorial line throughout pieces I have read.
Cuts through the usual marketing fluff that dominates this topic online, and a stop at astrorod kept the same clean approach going, this is the kind of writing that respects the reader’s time rather than wasting it on repetitive setups before finally getting to the point at hand which is what most sites do.
Genuinely useful read, the points are practical and easy to apply right away, and a quick look at velvettrailbazaar confirmed that this site is consistent in that approach, looking forward to digging through the rest of it when I get the chance to sit down properly later in the week or this weekend.
Coming back tomorrow when I can give this a proper read, the post deserves better attention than I can give right now, and a look at snapfork suggests there is plenty more here that deserves the same treatment, definitely a site I will be exploring properly over the next few days when I can.
My reading list is short and selective and this site is now on it, and a stop at lunarcode confirmed the placement, the short list of sites I read deliberately rather than encounter accidentally is something I curate carefully and adding to it is a real act of trust which this site has earned today.
Now adding this to a list of sites I want to see flourish, and a stop at fastgoodsbazaar reinforced that wish, the few sites I actively root for are sites that produce the kind of work I want more of in the world and this one has joined that small list based on what I have read so far.
Good quality through and through no rough edges and no signs of being rushed and a quick look at seobridge kept the same polish going the kind of site that respects its own brand by maintaining consistency across pages which is something I always appreciate as a reader looking for trustworthy information online today.
Came in for one specific question and got answers to three I had not even thought to ask, and a look at sagebay extended that bonus value pattern, the kind of resource that anticipates reader needs rather than just answering the literal question asked is the gold standard and this site reaches it.
Generally my comment to other readers about new sites is to wait and see but for this one I would jump to recommend now, and a look at smartcartarena reinforced that early recommendation, the speed at which a site earns my recommendation is itself a quality signal and this one has earned mine quickly clearly.
Now adding a small note in my reading log that this site is one to watch, and a look at emberkit reinforced the watch status, the few sites I track deliberately rather than encounter accidentally are sites I expect ongoing returns from and this one has cleared the bar for that elevated tracking based on what I read.
Picked a friend mentally as the audience for this and decided to send the link, and a look at cloudmeadowcollective confirmed the send was the right choice, choosing whom to share content with is a small act of curation that I take more seriously than the public sharing most platforms encourage these days online.
Reading this slowly in the morning before opening email, and a stop at lushstack extended that protected attention, content that earns the prime morning reading slot before the daily distractions begin is content with elevated status and this site has earned that prime slot consistently in my recent reading habits clearly.
Reading this confirmed a small detail I had been uncertain about, and a stop at glowjump provided the source for further checking, content that supports verification through citations or links rather than just asserting facts is more trustworthy and this site has clearly built its credibility through that kind of verifiable approach consistently.
Appreciated how the post felt complete without overstaying its welcome and a stop at maplecrestgoods confirmed that economical approach runs across the site knowing when to stop is a skill many writers never develop but here the discipline is obvious and welcome from the perspective of a busy reader trying to learn things efficiently.
Most posts I read end up forgotten within a day but this one is sticking, and a look at findyouranswers 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.
Reading this with my morning coffee turned into reading the related posts with my morning coffee, and a stop at crystalwindcollective stretched the morning further, content that pulls breakfast into a reading session rather than just accompanying it is content that has earned a higher claim on my attention than the average article does.
