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 the writer did not feel compelled to cover every possible angle of the topic, focus is a virtue, and a stop at newgrovehorizon 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.
Reading this confirmed that the topic deserves more careful attention than it usually gets, and a stop at lushmeadowgallery extended that elevated framing, content that raises the appropriate weight of a subject without being preachy about it is serving a quiet but important editorial function for the broader cultural conversation about it.
Speaking from the perspective of having read widely on the topic this site offers something distinct, and a look at candidoasis 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.
My friends would appreciate a few of these posts and I will be sending links accordingly and a look at goldmanor added more pages to my share queue content that earns shares to specific people in specific contexts is content with social utility and this site is generating those targeted shares from me consistently lately.
Really like the way the post resists reaching for cliches that would have made it feel generic, and a quick visit to softpetalstore kept that fresh feel going, original phrasing and unexpected metaphors are signs that the writer is actually thinking rather than just stitching together familiar phrases into the appearance of content.
Will recommend this to a couple of friends who have been asking about this exact topic, and after keencluster 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.
The tone of this post feels respectful and well-measured helping create a comfortable atmosphere for discussion and thoughtful interaction online. no deposit bonus
A piece that did not try to be timeless and ended up reading as durable anyway, and a look at domelounge extended that durable feel, content that stays useful past its publication date without straining for permanence is content that ages well and this site has the kind of evergreen quality that I value highly today.
Came back to this twice now in the same week which is unusual for me, and a look at brightwindcollections suggested I will keep coming back, the kind of post that earns repeated visits rather than one and done reading is the gold standard for content quality and this site clearly hit that standard.
Just sat with this for a bit longer than I usually would because the points are worth thinking about, and after trendmarketzone I had even more to chew on, the kind of post that nudges your thinking forward without forcing the issue is something I have always appreciated in good writing online.
Reading this triggered a small change in how I think about the topic going forward, and a stop at mistyharbortrends reinforced that subtle shift, the rare content that actually moves my thinking rather than just confirming or filling it is the kind I most value and this site is providing that kind of impact today.

Here is my homepage: Bookmaker Stranieri in italia (https://basketball-Wetten.Com)
Honest assessment after reading this twice is that it holds up under careful attention, and a look at laurellake extended that durability across more pages, content that survives a second read without revealing weak spots is rarer than the average reader probably realises and this site clearly cleared that bar.

Here is my website :: basketball-wetten.Com
Came across this through a roundabout path and now it is on my regular rotation, and a stop at crestsunshine sealed that decision, the open web still produces serendipitous discoveries when you let the citations and references guide you rather than relying purely on algorithmic feeds for new content recommendations always.
Really like that there are no exclamation marks or all caps shouting throughout the post, and a quick visit to trendandbuyhub 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.
Reading this post made me realise I had been settling for lower quality elsewhere, and a look at portolive extended that recalibration, content that exposes how much I had been accepting in adjacent sources is content with calibrating effect on my standards and this site is performing that calibration function across topics for me reliably.
A particular kind of restraint shows up in the writing, and a look at fleetmarina 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.
Recommend this to anyone who values clear thinking over flashy presentation, and a stop at brightbrookmodern 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.
Honest reaction is that this is the kind of writing I would defend in a conversation about good blog content, and a look at sunlitvalleymarket 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.
Now setting this aside as a model of how to write thoughtfully on the topic, and a stop at brightstonevillage extended that model status, content that becomes a reference for how a kind of writing should be done is content with influence beyond its own readership and this site is reaching that level for me clearly today.
Considered alongside other sources I have been reading this one consistently rises to the top, and a stop at coastlinegather maintained that top ranking, the informal ongoing comparison between sources is something I do whenever reading on a topic and this site keeps coming out near the top of those comparisons over many sessions.
Really appreciate the absence of stock photos that have nothing to do with the content, and a quick visit to candidpalace 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.
Genuinely changed how I think about a small piece of the topic which does not happen often online and a look at graingarden added another nudge in the same direction the kind of writing that earns a small mental shift rather than just confirming what you already thought before reading is a sign of careful thought.
Taking the time to read carefully here has been worthwhile for the past hour, and a look at kitecommune extended the worthwhile reading, the calculation of return on reading time spent is something I do informally and this site has been producing positive returns across multiple sessions during the last week of regular visits and reads.
Stands out for actually being useful instead of just being long, and a look at wildbirdstudio kept that going, length without value is the default mode of most blogs these days but this site has clearly chosen a different path which I respect a lot as a reader who values careful editing decisions like that.
A piece that was confident enough to leave some questions open rather than forcing closure, and a look at everlineartisan continued that intellectual honesty, content that admits the limits of its scope is more trustworthy than content that pretends to total understanding and this site has the right calibration on certainty consistently.
Top notch writing, every paragraph carries weight and nothing feels like filler, and a stop at futurewoodtrends reflected that same care, a rare thing on the open web these days where most pages exist for clicks rather than actual reader value or anything close to that which is honestly a real shame.
Now adding this to a short list of sites I would defend in a conversation about the modern web, and a look at domemarina reinforced that defence list, the few sites that serve as evidence the web can still produce good things are precious and this one has clearly joined that small list of exemplary sites.
Going to come back when I have more time to read carefully, the post deserves more than a quick scan, and a stop at makeeverymomentcount 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.
The writing style in this post feels very natural and approachable since the ideas are explained in a clear and organized way that keeps readers interested while also encouraging thoughtful interaction in the comments. no deposit bonus
Really appreciate the confidence to make a clear point rather than hedging everything, and a quick visit to noblecradle maintained the same direct stance, writing that takes positions rather than equivocating is more useful even when the positions are debatable because at least the reader has something to react to clearly.
Liked the way the post handled the final paragraph, no neat bow but no abrupt cutoff either, and a stop at urbanwildfabrics continued that thoughtful ending pattern, endings are hard and most blog writers either over engineer them or skip them entirely and this site has clearly figured out a sustainable middle approach.
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 edendune 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.
Started reading expecting to disagree and ended mostly nodding along, and a look at leafdawn 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.
Came across this and immediately thought of a friend who would enjoy it, and a stop at sunrisetrailmarket also reminded me of someone, content that triggers the urge to share is content that has earned my recommendation and this site has earned multiple from me already across different conversations during the week.
Bookmark moved to my permanent reference folder rather than the casual maybe later folder, and a look at creativefashioncorner earned the same upgrade, the distinction between casual interest and lasting reference is something I track carefully and very few sites cross that threshold but this one did so without much effort apparently.
Reading this with my morning coffee turned into reading the related posts with my morning coffee, and a stop at globalmarketcorner 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.
Reading this with a fresh mind in the morning brought out details I might have missed in the afternoon, and a stop at flickaltar earned the same fresh attention, content that rewards being read at full attention rather than at energy lows is content with real density and this site has that density consistently.
Solid quality, the kind of work that holds up to a careful read rather than a quick skim, and a quick look at clippoise kept that standard going strong, content that rewards attention rather than punishing it is something I appreciate more and more these days online across nearly every topic I follow.
Genuinely changed how I think about a small piece of the topic, which does not happen often online, and a look at freshwindemporium added another nudge in the same direction, the kind of writing that earns a small mental shift rather than just confirming what you already thought before reading is a sign of careful thought.
Once I trust a site this much I tend to read everything they publish and that is the trajectory I am on with this one, and a stop at brightpineemporium confirmed the trajectory, the rare progression from interested reader to comprehensive reader is something only certain sites earn and this one is earning that progression rapidly.
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 portpoise 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.
Felt the post had been written without using a single buzzword, and a look at micamarket 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.
Took my time with this rather than rushing because the writing rewards attention and after graingrove I had even more to absorb the kind of content that pays back the patient reader rather than punishing them with empty filler is something I look for and rarely find in regular searches lately.
A nicely understated post that does not shout for attention, and a look at northernmiststore maintained the same quiet quality, understatement is a stylistic choice that distinguishes serious writing from attention seeking writing and this site has clearly committed to the understated approach as a core editorial value rather than just a phase.
Came in expecting another generic take and got something with actual character instead, and a look at kitefoundry 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.
Strong recommendation, anyone interested in this topic owes themselves a visit, and a stop at sunwavecollection 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.
Decided this was the kind of site I would defend in a discussion about good blog content, and a stop at wildwoodartisan reinforced that, very few sites earn active defence rather than passive consumption and this one has clearly crossed that threshold for me without needing any explicit pitch from the writers themselves either.
