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:
Now placing this in the same category as a few other sites I have come to trust, and a look at learnandgrowstrong continued the placement decision, the small category of fully trusted sites is one I extend rarely and only after multiple positive reading sessions and this site has earned the category placement methodically over time.

Well done, the kind of post that makes you slow down and actually read instead of skimming for keywords, and a look at chairchampion kept me reading carefully too, that is a sign of writing that has been crafted rather than churned out for an algorithm to see today and tomorrow.
sportfogadó oldalak élő fogadás magyar engedély Nélkül legjobb engedély nélkül magas oddsokkal
Definitely returning here, that is decided, and a look at discovergrowthdirectionnow only made the case stronger, this is one of those rare websites that rewards regular visits rather than feeling stale after the first read which is something I cannot say about most of the places I bookmark today across all my topics.
Felt the writer did the homework before publishing, the references hold up, and a look at createbetteroutcomesnow continued that documented care, content with traceable claims rather than vague assertions is the kind I trust and the lack of bald assertion in this post is one of its quietly impressive qualities for me.
Reading this brought back the satisfaction I used to get from blogs ten years ago, and a stop at forwardactionframework kept that nostalgic quality alive, sites that capture what was good about an earlier era of internet writing are increasingly precious and this one is doing that without feeling like a deliberate throwback at all.

my blog post: Basketball-wetten.com
Reading this gave me a quiet moment of intellectual pleasure that I had not been expecting, and a stop at learnandscaleprogress extended that pleasure across more pages, the unexpected reward of stumbling into careful writing is one of the small ongoing pleasures of reading the open web and this site is delivering it reliably.
If quality blog writing is dying as people sometimes claim then this site is one piece of evidence that it has not died yet, and a look at buildfocusedmomentum extended that evidence, the broader cultural question about online writing has empirical answers in specific sites and this one is contributing to a more optimistic answer overall.
Just wanted to drop a quick note saying this was a useful read on a topic I have been circling, no fluff, and a stop at findmomentumnext added a few extra points that fit the same simple style which makes the whole site feel coherent rather than thrown together by many different writers with different goals.

However many similar pages I have read this one taught me something new, and a stop at buildforwardclarity added more new material, content that contributes genuinely fresh information rather than recycling what is already widely available is content with real informational value and this site is providing that informational freshness at a notable rate.
дезинфекция от тараканов в москве уничтожение клопов цена москва
Easy to recommend, the content speaks for itself without needing additional praise from me, and a stop at createforwardthinking only adds more reasons to send people this way, the kind of generous resource that benefits its readers without demanding anything in return is increasingly rare and worth recognising clearly today across the broader open internet.
Speaking from the perspective of having read widely on the topic this site offers something distinct, and a look at explorefutureopportunitypaths 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.

Thank you for not assuming the reader already knows everything, the explanations meet me where I am, and a look at createwithintention 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.
Reading this slowly to absorb the structure and the structure is doing real work alongside the words and a look at palmmills 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.
Really appreciate the lack of pop ups, modals, cookie banners stacking on top of each other, and a quick visit to brightbanyan confirmed the same clean approach across the rest of the site, technical decisions about user experience are part of what makes content actually pleasant to engage with for sure.
A piece that brought a sense of order to a topic I had been finding chaotic, and a look at opaldunes 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.
Reading this prompted me to clean up some old notes related to the topic, and a stop at graingrove extended that organising urge, content that triggers personal organisation rather than just consuming attention is content with motivating energy and this site has the kind of clarity that prompts active follow up rather than passive consumption.
Refreshing change from the usual sites covering this topic, no clickbait and no padding, and a stop at focuscreatesprogress confirmed the difference, this place clearly has its own voice rather than copying the formulas everyone else uses to chase clicks online which is becoming increasingly rare these days across nearly every popular subject.
Appreciate the work that went into laying this out so clearly, every section earns its place without filler, and a look at curiopacts 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.
Thank you for the genuine effort here, it shows in every paragraph and not just the headline, and after my visit to portguild I was sure this site cares about getting things right rather than chasing clicks, which is the main reason I will come back later this week to read more.
Thanks for putting this online without locking it behind email signups or paywalls, and a quick visit to lobbydawn kept that open feel going, content that trusts the reader to come back rather than gating access is the kind of approach I will reward with regular return visits over time happily.
Granted my mood today might be elevating my reading experience but I still think this is genuinely good, and a stop at zingtorch reinforced that even discounted assessment, controlling for the mood adjustment that affects content perception this site still reads as substantively above average across multiple pieces I have read carefully today.
Thanks for keeping the writing direct without losing the warmth that makes content feel human, and a stop at fernbureau carried both qualities forward, balancing professionalism and personality is a rare skill and the writers here have clearly figured out how to consistently land it across many posts which I notice.
Following a few of the internal links revealed more posts of similar quality, and a stop at micapacts 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.
Honestly this hits the sweet spot between detail and brevity, no rambling and no shortcuts, and a quick visit to draftport kept that going across the related pages, the kind of place that respects your attention without trying to grab it through cheap tactics or attention seeking design choices that get tired fast.
Came away feeling slightly smarter than I was when I started, that is a real win, and a stop at findyourwinningdirection added a bit more to that, the rare site that actually transfers some of its knowledge to the reader in a way that sticks rather than just creating an illusion of learning briefly.
Decided to write a short note to the author if there is contact info anywhere and a stop at findgrowthdirections extended that intention the urge to thank the writer directly is a strong signal of content quality and this site has triggered that urge in me today which is a fairly rare event for my reading.
Solid value packed into a relatively short post, that takes skill, and a look at buildforwardthinkingmomentum continues the dense useful content across more pages, this site clearly understands that respecting reader time is itself a form of generosity which is something most blog operations seem to have forgotten lately across the wider open web.
Glad I clicked through from where I did because this turned out to be worth the time spent, and after ideaswithtraction I had a fuller picture, the kind of content that earns its visitors through delivering value rather than chasing them through aggressive advertising or constant pop ups appearing everywhere on the screen lately.
Mais um dia positivo. Bati a meta no Blackjack e a grana já tá na mão. Respeita o stop-win.
Now wishing I had found this site sooner, and a look at createforwardexecutionsteps extended that mild regret, the calculation of how many years of good content I missed by not finding the right sources earlier is one I try not to make too often but it does come up sometimes when I find sites this good.
High quality writing, no marketing speak and no buzzwords that mean nothing, and a stop at tomatotactic kept that going, simple direct content that actually communicates something is harder to find than it should be and this is one of the rare places that gets it right consistently across many different posts.
Really like that there are no exclamation marks or all caps shouting throughout the post, and a quick visit to startsmartgrowth maintained the same calm voice, restraint in punctuation signals confidence in the content and this site clearly trusts its substance to do the persuading rather than relying on typographic emphasis.

Felt slightly impressed without being able to point to one specific reason, and a look at momentumbymindset 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.

Now adding the homepage to my regular check rotation rather than waiting for individual links to find me and a stop at domelegends confirmed the rotation upgrade the move from passive discovery to active checking is a vote of confidence in a sites ongoing quality and this site has earned that active engagement clearly.
Granted I am giving this site more credit than I usually give new finds, and a look at buildsmartprogress 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.
A piece that reads like it was written for me without claiming to be written for me, and a look at edendomes produced the same fit, when the writer audience match clicks naturally without being engineered through demographic targeting you know the writing is solid and this site has that natural fit consistently for me.
Now noticing that the post never raised its voice even when making a strong point, and a look at frostcoasts continued that calm volume, content that can make important points without resorting to typographic emphasis or emotional appeal is content that trusts its substance to do the work and this site has that confidence consistently.
My time on this site has now extended past what I had budgeted, and a stop at portguild keeps extending it further, content that overstays its budget in my schedule is content that has earned the extra time and this site has been earning extra time across multiple visits to the point where my schedule needs adjustment.
Worth recommending broadly to anyone who reads on the topic, and a look at lobbydawn only confirms that, the rare combination of accessibility and depth in this site makes it suitable for both newcomers and people who already know the area which is hard to pull off in any blog format today and rarely managed.
Reading this gave me something to think about for the rest of the afternoon, and after grippalace I had even more to mull over, the kind of post that lingers in the background of your day rather than evaporating immediately is genuinely valuable in an attention economy that punishes depth rather than rewarding it.
Thanks for the clean writing, no broken sentences and no awkward translations like some other sites have, and a quick stop at ideasintoexecution 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.
