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:
Glad to have another data point on a question I am still thinking through and a look at directioncraft 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.
Genuine reaction is that this site clicked with how I like to read, and a look at directionclarifiesaction kept that comfortable fit going, sometimes you find a place online whose editorial decisions just align with your preferences and when that happens it is worth recognising and supporting through repeat engagement consistently going forward.
Probably the best thing I have read on this topic in the past month, and a stop at claritycreatesflow 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.
Going to come back when I have more time to read carefully, the post deserves more than a quick scan, and a stop at trustcoregroup reinforced that, this is the kind of site that rewards a slower read which is hard to find in this fast paced corner of the internet but really worthwhile.
My usual pattern is to skim and bounce but this site has reset that pattern temporarily, and a stop at directionaldrive 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.
Now feeling mildly impressed in a way I do not quite remember feeling about a blog in a while, and a stop at growthcraft extended that mild impression, content that produces specific positive emotional responses rather than just neutral information transfer is content with extra dimensions and this site has those extra dimensions clearly.
Now feeling the post has earned a proper recommendation rather than a casual mention, and a stop at momentumflow reinforced the recommendation strength, the difference between mentioning and recommending is a small editorial distinction I observe in my own conversations and this site has earned the upgraded recommendation level from me confidently today.
Going to share this with a friend who has been asking the same questions for a while now, and a stop at visionforward 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.
Now recognising the editorial wisdom of letting some questions remain open at the end, and a look at actioncreatesvelocity 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.
Quality work here, the post reads cleanly and the points stay focused throughout, and a stop at ideascreatepathways kept the standard high, you can tell the writer cares about the final result rather than just hitting publish for the sake of having something new on the page to feed the search engines.
Liked the way the post got out of its own way, and a stop at focusalignment 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.
Now feeling slightly more committed to my own careful reading practices having read this, and a stop at bondedalliance reinforced that commitment, content that models the kind of attention it deserves is content that calibrates the reader and this site has clearly raised my own bar for what to bring to good writing today.
Now setting aside time on my next free afternoon to read more from the archives, and a stop at unitykeystone confirmed that time will be well spent, the rare site whose archive deserves a dedicated reading session rather than just casual sampling is the kind of resource worth scheduling around and this one qualifies clearly.
Felt mildly happier after reading, which sounds silly but is true, and a look at trustcircle extended that small mood lift, content that improves rather than degrades my mental state is content I want more of and the cumulative effect of reading sites that lift versus sites that drag is real over time.

Now thinking about how to apply some of this to a project I have been planning, and a look at stonebridgecapital added more material for the planning, content that connects to my actual creative work rather than just being interesting in the abstract is the kind that earns priority placement in my reading rotation consistently going forward.

Honestly enjoyed reading this more than I expected to when I first clicked through, and a stop at strategymap kept that pleasant surprise going, sometimes you stumble onto a site that just clicks with how you like to read and this is one of those for me right now today which is great.
Excellent post, balanced and well organised without showing off, and a stop at digitalspark 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.
Skipped the related products section because there was none, and a stop at directionguidesmotion also lacked any aggressive monetisation, content that is not constantly trying to convert me into a customer or subscriber is content that has confidence in its own value and that confidence shows up as a different reading experience.
Just want to flag that this was useful and not bury the appreciation in caveats, and a look at signalclarifiesaction 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 not to comment because the post said what needed saying, and a stop at kavqaro continued that complete feel, content that does not invite obvious additions or corrections from readers is content that has been carefully considered and this site appears to consistently produce pieces that satisfy rather than provoke unnecessary follow ups.
Worth flagging this post as worth a careful read rather than a casual skim, and a stop at capitalbonded earned the same careful approach, the few sites that warrant slower reading are sites I now treat differently from the daily content stream and this one has clearly moved into that elevated treatment category.
Really like that the writer trusts the reader to follow simple logic without restating every previous point, and a stop at dreamcreator 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.
Came here from a search and stayed for the side links because they were that interesting, and a stop at buildclearoutcomes took me even further into the site, the kind of organic exploration that good content invites is something most sites kill through aggressive interlinking and pushy navigation choices rather than relying on quality.
Took longer than expected to finish because I kept stopping to think, and a stop at unitybondworks did the same to me, content that provokes thought rather than just delivering information is in a different category and the team here is clearly working at that higher level rather than just cranking out posts.
Now organising my browser bookmarks to give this site easier access, and a look at bondedharvest 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.
Liked the careful word choice throughout, every term seemed picked for a reason rather than thrown in casually, and a stop at bondedfuturepath continued that precise style, this kind of attention to small details is what separates careful writing from the usual rushed content that dominates blog spaces today across pretty much every topic I follow.
Picked this site to mention to a colleague who would benefit, and a look at growthunlockedforward added more material I will pass along, recommending sites to colleagues is a higher bar than recommending to friends because the professional context demands more careful curation and this site cleared the professional bar without me having to think.
Now thinking about how to apply some of this to a project I have been planning, and a look at bondedlegacy added more material for the planning, content that connects to my actual creative work rather than just being interesting in the abstract is the kind that earns priority placement in my reading rotation consistently going forward.
Solid endorsement from me, the writing earns it, and a look at visionengine continues to earn it across the broader site too, the kind of operation that maintains quality across many pages rather than just one viral post is a sign of serious commitment and that is what I see here clearly across what I read.
Liked that the post resisted a sales pitch ending, and a stop at capitalbondgroup maintained the no pitch approach, content that ends without trying to convert me into a customer or subscriber is content that has confidence in its own value and this site is clearly playing the long game on reader trust.
Strong recommendation, anyone interested in this topic owes themselves a visit, and a stop at growthframework extends that recommendation across more of the site, this is the kind of resource that makes me more optimistic about the state of the open web than I usually am these days actually for once which is genuinely refreshing.
Really appreciate the absence of stock photos that have nothing to do with the content, and a quick visit to focusdefinesdirection maintained the same restraint, visual filler is a tell that the writing cannot stand on its own and the lack of it here suggests the team has confidence in their content quality alone.
Recommend this to anyone who values clear thinking over flashy presentation, and a stop at capitalbondworks continued in the same understated way, this site has its priorities in the right place which makes it worth supporting through repeat visits and recommendations rather than just one passing read today before moving on quickly elsewhere.
Definitely a recommend from me, anyone curious about the topic should check this out, and a look at actiondirection adds even more reason for that, the depth and quality combine to make this site one I will be pointing people toward whenever similar conversations come up over the months ahead at work or socially.

Now realising this site has been quietly doing good work for longer than I knew, and a look at growthmovesclearly suggested an archive worth exploring, sites with deep archives of consistent quality represent a different kind of resource than sites with viral hits and this one looks like the durable kind based on what I see.
Better than the average post on this subject by some distance, and a look at progresslane 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.
Skipped the TLDR thinking I would read everything anyway, and ended up enjoying the path through the full post, and a stop at claritystrategy similarly rewarded the patient read, summaries are useful but the journey through good writing is part of what makes the destination feel earned rather than just delivered cleanly.

Just want to record that this site is entering my regular reading list, and a look at focuscreatesmomentum confirmed it deserves the spot, my regular reading list is short and well curated and adding to it requires meeting a fairly high quality bar that this site has clearly cleared without much effort apparently.
Following a few of the internal links revealed more posts of similar quality, and a stop at directionguidesaction 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.
Now feeling confident enough in this site to use it as a reference point for evaluating others on the same topic, and a look at forwardmotiondefined continued the comparison friendly quality, sites that serve as quality benchmarks for their topic are precious and this one has clearly become a benchmark for me on this particular subject area.
Thanks for the readable length I finished it without checking how much was left and a stop at strategyalignment kept me reading the same way when I stop noticing the length of a piece because the content is engaging enough to sustain attention without willpower the writer has done their job well today.
Reading this felt productive in a way most internet reading does not, and a look at claritysystem continued that productive feeling, sometimes the open web feels like a waste of time but sites like this remind me why I still bother to look around rather than retreating to old reliable sources for everything I need.

Now feeling slightly more committed to my own careful reading practices having read this, and a stop at ideasneedmotion reinforced that commitment, content that models the kind of attention it deserves is content that calibrates the reader and this site has clearly raised my own bar for what to bring to good writing today.
Approaching this with the usual skepticism I bring to new sites and being slowly persuaded, and a stop at momentumshift continued that gradual persuasion, the careful path from skeptical reader to genuine fan is the only one I trust and this site has walked me along that path through patient consistent quality across pieces.
