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:
Will recommend this to a couple of friends who have been asking about this exact topic, and after swiftmaplecorner I have even more reason to do so, the kind of site that earns word of mouth rather than chasing it through aggressive marketing or paid placements is always a treat to find online.
A clean read with no irritations, and a look at linksurge continued that frictionless quality, the absence of small irritations is something I notice only when present elsewhere and this site is one of the rare places where everything just works and lets me focus on the substance rather than fighting the format.
Working through this site has been a small antidote to the shallow content that fills most of my reading time, and a stop at rankchart extended that antidote function, sites that quietly improve the average quality of my reading by being themselves are sites worth supporting through return visits and recommendations consistently.
Honestly this was a good read no jargon and no padding and a short look at seoquest 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.
A piece that did not lean on the writer credentials or institutional backing, and a look at shopcoremarket maintained the same focus on substance, content that earns trust through quality rather than through name dropping is the kind I find most persuasive and this site is clearly playing on the substance side of that distinction.
My usual pattern is to skim and bounce but this site has reset that pattern temporarily, and a stop at quartzmeadowmarketgallery maintained the slower reading mode, content that changes how I read is content with structural influence and this site has clearly nudged my reading behaviour toward something better at least for the duration of these visits.
A well calibrated piece that knew its scope and stayed inside it, and a look at findsomethingunique maintained the same scope discipline, scope creep is one of the failure modes of long blog posts and this site has clearly invested in the editorial discipline to prevent it which shows up in tightly contained pieces.
Thanks for not padding this with the usual filler intros and outros that every other blog seems to require, and a quick visit to expandyourmind 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.
Closed it feeling I had taken something away rather than just consumed something, and a stop at trendinggoodsmarket extended that taking away feeling, the difference between content I extract value from and content I just pass through is something I track informally and this site is consistently in the value extraction column for me.
Will be back, that is the simplest way to say it, and a quick visit to linkslate reinforced the decision, this site has earned a spot in my regular rotation alongside a few other reliable places I check when I want something genuinely informative without all the usual modern web noise getting in the way.
A genuine compliment to the writer for keeping the post focused on what mattered, and a look at leadslate continued that disciplined focus, focus is a editorial choice that compounds across many small decisions and this site has clearly made those small decisions consistently across what I have read so far this week here.

My site – wetten basketball pro a
Started thinking about my own writing differently after reading and a look at cloudridgegoods continued that reflective effect content that influences how I work rather than just informing what I know is content with the highest kind of impact and this site has triggered some of that reflective influence today on me.
Stands apart from similar pages by actually being useful, that is high praise these days, and a look at seoscope kept that standard going, you can tell when a site is built around the reader versus around metrics and this one clearly belongs to the first category for sure based on what I read.
A piece that left me thinking I had been undercaring about the topic, and a look at seofuel reinforced that mild concern, content that raises the appropriate weight of a subject without being preachy about it is doing important work and this site is providing that gentle elevation of attention for me consistently.
Now adjusting my mental model of how the topic fits into the broader landscape, and a look at leadtower extended that adjustment, content that affects my structural understanding rather than just my factual knowledge is content with deeper impact and this site is providing those structural updates at a meaningful rate consistently across topics.

Рабочие места переговорные комнаты быстрый интернет и удобная инфраструктура. Подходит для фрилансеров предпринимателей стартапов и команд которым нужен гибкий офис.
Just want to flag that this was useful and not bury the appreciation in caveats, and a look at windcrestcollective earned the same direct praise, recognising good work without hedging it with criticism is something I try to practice because over qualified compliments tend to read as backhanded and miss the point sometimes.
Decided to subscribe to the RSS feed if there is one, and a stop at linktrail confirmed that decision, content that I want delivered to me proactively rather than just remembered when I have time is content that has earned a higher level of commitment from me as a reader looking for reliable sources.
Skipped the comments section but might come back to read it, and a stop at prismoakcollective hinted at a quality reader community, sites where the comments are worth reading separately from the post are increasingly rare and signal a particular kind of audience that has grown around the editorial vision over time gradually.
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 yourfashionoutlet 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.
While exploring various fashion focused ecommerce platforms that emphasize style and usability, I found a clean and modern interface that feels easy to navigate, and Global Fashion Finds hub delivers a smooth browsing experience overall – The website presents fashion items in a visually appealing layout, making browsing effortless while maintaining a smooth and enjoyable shopping experience for users.
Felt the writer did the homework before publishing the references hold up and a look at adstrike 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.
Glad to have another data point on a question I am still thinking through, and a look at linkladder added two more, content that acknowledges its place in a wider conversation rather than pretending to settle the question alone is intellectually honest in a way that I wish was more common across the open web.

Started reading expecting to disagree and ended mostly nodding along, and a look at royalgoodsarena 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.
Looking for similar voices elsewhere has come up empty in my recent searches, and a stop at rankrally extended the search frustration, the rare site that does what no other does in quite the same way is precious and this one has clearly developed a particular approach that I have not been able to find duplicates of.
Genuine reaction is that I will probably think about this on and off for a few days, and a look at modernoutfitstore added fuel to that, the best content lingers in your head after you close the tab rather than evaporating immediately and this site clearly knows how to write that kind of memorable content.
Recommended to anyone working in or curious about this area, the depth and clarity combine well, and a look at twilightcovecollective keeps that going across more pages, the kind of site that earns regular visits rather than chasing trends has my respect because it suggests genuine commitment to the topic itself rather than to chasing trends.
Started this morning and finished at lunch with a small sense of having spent the time well, and a look at seovibe extended that satisfaction into the afternoon, content that fits naturally into the rhythm of a working day rather than demanding a dedicated reading block is increasingly the kind I prefer.
Now recognising that this site has earned a place in the small group of resources I treat as authoritative, and a stop at floraharborvendorparlor confirmed that placement, the difference between resources I trust and resources I just consume is real and this site has clearly moved into the trusted category through consistent quality over time.
Worth flagging that the writing rewarded a second read more than I expected, and a look at adgain produced the same second read benefit, content with hidden depths that emerge only on careful rereading is rare in the modern blog space and this site has clearly invested in that level of compositional density throughout.

Appreciate how nothing here feels copied or pieced together from other places, the voice is consistent and the tone stays human, and after I checked ranktap I noticed the same style holds, which is a small detail but it makes the whole experience feel personal rather than like another generic site.
A piece that handled a controversial angle without becoming heated, and a look at windspirecollective continued that calm engagement, content that can address contested topics without inflaming them is doing rare diplomatic work and this site has clearly developed the editorial maturity to handle sensitive material with the appropriate temperature of writing throughout.
Even just sampling a few posts the consistency is what stands out and a look at linkgrit confirmed the broader pattern sites where every piece I sample lives up to the standard set by the others are sites with serious quality control and this one has clearly invested in whatever editorial process produces that consistency reliably.
Now appreciating that I did not feel exhausted after reading, and a stop at seospark extended that energising quality, content that leaves me with more attention than it consumed is rare and the gap between draining and energising content is real over the course of a typical day spent reading widely online.
Reading this felt easy in the best way, no friction and no confusion at any point, and a stop at radiantmaplestore 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.
Left me wanting to read more rather than feeling burned out, that is a good sign, and a look at growtogethercommunity confirmed there is plenty more here to explore, the kind of writing that builds appetite rather than killing it which is a rare quality on the modern open internet today across most categories of content.
Really appreciate the lack of pop ups, modals, cookie banners stacking on top of each other, and a quick visit to seofunnel 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.

My web-site; sicher wetten gewinnen (Theda)
Found something quietly useful here that I expect to return to, and a stop at trendinggoodsmarket added more of the same, content with quiet utility ages well in a way that flashy hot takes do not and I have learned to weight quiet utility much higher when deciding what to bookmark for later use.
Strong recommendation from me, anyone curious about the topic should make time for this, and a look at startyourjourneytoday only sharpens that recommendation further, the kind of resource that holds up against careful scrutiny rather than crumbling at the first critical question is rare and worth pointing other people toward when the topic comes up.
Considered against the flood of similar content this one stands apart in important ways, and a stop at leadspot extended that distinctive feel, sites that find their own corner of a crowded topic and stay there are sites worth following and this one has clearly carved out its own space and committed to defending it carefully.
Felt the post had been written without using a single buzzword, and a look at rankfunnel continued that clean vocabulary, content free of jargon and trendy phrases reads better and ages better and this site has clearly committed to a vocabulary that will not feel dated in three years which is impressive editorially.
Reading this site over the past week has changed how I evaluate content in this space, and a look at adladder extended that recalibration, the standards I bring to reading on the topic have shifted upward as a direct result of regular exposure to this kind of work and that shift will outlast any single reading session.
Now considering whether the post would translate well into a different form, and a look at buypathmarket suggested similar versatility, content that could move into other media without losing its substance is content that has been built around ideas rather than around format and this site reads as idea first throughout posts.
A thoughtful piece that did not strain to be thoughtful, and a look at creativechoicehub 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.
Reading this confirmed a hunch I had been carrying about the topic without having articulated it, and a stop at twilightcreststore extended the confirmation, content that gives shape to fuzzy intuitions is doing the rare work of making private thoughts public and this site is providing that articulating service consistently for me lately.
Came away with some new perspectives I had not considered before and after cloudridgegoods those ideas felt more complete the kind of content that stays with you a little while after reading rather than slipping out the moment you switch tabs and move on with your day to whatever comes next.
