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:



Bookmarked the page and the homepage too because clearly there is more to explore here, and a quick stop at brightfashionfinds only made that more obvious, this is the kind of place I want to dig through over a weekend rather than rushing through during a coffee break tomorrow morning before getting back to work.
During my search through different logistics and online delivery platforms, I eventually opened trusted shipment tracker as the structure appeared clean and practical – The whole browsing experience felt pleasant today, and the website design looked modern, welcoming, and easy for users to explore without confusion or delays.
Now realising the topic deserved better treatment than it has been getting elsewhere, and a look at discovermoretoday extended that broader recognition, content that exposes the gap between actual quality and average quality elsewhere is doing the quiet work of raising standards and this site is contributing to that elevation in its own corner.
Pass this along to colleagues if the topic comes up, the framing here is sensible, and a stop at dailytrendspot adds more useful angles to share, the kind of content that improves conversations rather than just feeding them is what makes a resource genuinely valuable in professional contexts going forward over time and across project boundaries too.

During comparison of bargain and savings websites, I noticed a platform that feels simple and engaging for everyday shoppers, and Offer discovery outlet provides a smooth browsing experience overall – The interface is responsive, categories are organized logically, and users can explore deals without confusion or complicated navigation.
During a casual search for informative websites and collaborative learning spaces, I came across friendly knowledge portal – The website design was simple and welcoming, with well arranged content that made it easy to explore various sections while maintaining a positive and smooth user experience overall.
Solid little post the kind that does not need to be flashy because the substance is doing the work and a look at discoverhiddenopportunities kept that quiet confidence going across the site this is what writing looks like when the writer trusts the content to land on its own without theatrics or unnecessary attention seeking behaviour.
Good quality through and through, no rough edges and no signs of being rushed, and a quick look at learnandimprove 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.
A piece that handled multiple complications without becoming confused, and a look at globaltrendstore continued that organisational clarity, holding multiple threads in a single piece without losing any of them is a sign of skilled writing and this site has clearly developed the editorial discipline to manage complexity without sacrificing readability throughout.

Reading this between two meetings turned out to be the highlight of the morning, and a stop at growbeyondlimits continued that highlight quality, content that outshines the structured parts of a working day is doing something well beyond ordinary and this site has produced multiple such highlights for me already this week alone.
A handful of memorable phrases from this one I will probably use later, and a look at discovergreatideas added a couple more, content that contributes language to my own communication rather than just facts is content with a different kind of utility and this site is providing that linguistic utility consistently across what I read.

Spent a few minutes here and came away with a clearer picture of the topic, the writing keeps things simple without dumbing them down, and after a stop at everydayshoppinghub the rest of the points lined up neatly which is something I appreciate when I am short on time and need answers fast.
Now planning a longer reading session for the archives, and a stop at urbanfashioncorner confirmed the archives are worth that longer commitment, sites with archives I want to read deliberately rather than just sample are rare and this one has clearly earned that level of interest based on the consistency of what I have already read.
Looking for similar voices elsewhere has come up empty in my recent searches, and a stop at yourvisionmatters 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.
While exploring online clothing stores and fashion marketplaces, I discovered fashion lookbook hub embedded in a curated section, and the website felt smooth as product browsing remained clean, structured, and enjoyable for users.
If patience for careful reading is rare these days finding sites that reward it is rarer still, and a stop at newtrendmarket extended that rare reward, the diminishing returns on shallow content reading have made me more selective about where to spend reading time and this site is meeting the higher selectivity bar consistently.
Spent a few minutes here and came away with a clearer picture of the topic, the writing keeps things simple without dumbing them down, and after a stop at nexshelf the rest of the points lined up neatly which is something I appreciate when I am short on time and need answers fast.
If I had to summarise the editorial sensibility of this site in a few words it would be careful and human, and a look at buildyourpotential extended that summary feeling, capturing the essence of a sites approach in brief is hard but this site has a clear enough identity that the summary comes naturally enough.
A quiet kind of confidence runs through the writing, and a look at linkbeacon carried that same understated assurance, confidence without bragging is the most attractive register for online writing and the writers here have clearly developed it through practice rather than affecting it through stylistic tricks that would feel hollow eventually.
Glad the writer did not feel compelled to cover every possible angle of the topic, focus is a virtue, and a stop at smartshoppingplace 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.

During my review of boutique-style ecommerce websites, I noticed a well-balanced design approach with strong usability, and Haven Blossom online store provides a clean navigation system – The platform feels modern and easy to use, allowing users to explore products smoothly without distractions or clutter affecting the browsing experience at any stage.
If I were to recommend a starting point for the topic this site would be near the top of my list, and a stop at dreamcreateachieve reinforced that recommendation status, the small list of starting point recommendations I keep for friends asking about topics is short and this site is now firmly on it.
Thank you for not assuming the reader already knows everything the explanations meet me where I am and a look at styleandchoice 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.
While checking various online shopping platforms earlier today, I came across helpful ridge urban store and appreciated the simple navigation, where products felt accessible and website performance stayed stable across all pages.
Useful information presented in a way that does not feel like a sales pitch, that is what I appreciated most, and a stop at growyourmindset was the same, no upsell and no fake urgency just steady content laid out properly for someone trying to actually learn from it rather than just be sold to.
Polished and informative without feeling overproduced, that is the sweet spot, and a look at groweverymoment hit it again, you can tell when a site has been built with care versus thrown together for the sake of having something to put online and this is clearly the former approach taken by the team.
black ops darknet https://sites.google.com/view/nexusmarketplace
Found something new in here that I had not seen explained this way before, and a quick stop at findpeaceandpurpose expanded the idea even further, the kind of writing that nudges your thinking forward a bit without forcing the issue is exactly what I look for online today and rarely actually find anywhere.
Earlier today I browsed through numerous online stores before discovering featured shopping resource, and I really liked how straightforward the navigation felt thanks to categories that made finding products simple and efficient.
Glad the writer kept this short rather than padding it out, the points stand on their own without needing extra context, and a look at explorelimitlesspossibilities kept the same approach going, brevity is a sign of confidence in the substance and the team here clearly trusts their content to land without filler.
While exploring urban fashion e-commerce platforms, I found a website that feels modern and visually appealing, and City Style Market delivers smooth navigation overall – The platform showcases stylish streetwear collections designed for modern lifestyles, making it easy for users to find fashion inspiration.
Looking through the archives suggests this site has been doing this for a while at this level, and a look at discoverpossibility confirmed the long term consistency, sites that have maintained quality across years rather than just a recent stretch are sites with serious editorial discipline and this one has clearly been at it for a while.

Now realising this site has been quietly doing good work for longer than I knew, and a look at yourvisionawaits 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.
Genuinely useful read, the points are practical and easy to apply right away, and a quick look at modernhometrends 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.
Closed the laptop after this and let the ideas settle for a few hours and a stop at trendywearstore similarly rewarded reflective time content that benefits from sitting with rather than racing past is the kind I want more of and the kind that this site appears to consistently produce week after week here.

Worth flagging that this approach to the topic is fresh without being contrarian, and a stop at stayfocusedandgrow extended the same fresh angle, finding original perspective on familiar subjects is rare and this site has clearly developed its own way of seeing rather than echoing the dominant takes from elsewhere consistently.
Started believing the writer knew the topic deeply by about the second paragraph, and a look at thepowerofgrowth reinforced that confidence, the speed at which a writer establishes credibility through their writing is a useful quality signal and this writer establishes it quickly and quietly without resorting to credential dropping or self promotion.
Even on a quick first read the substance of the post comes through, and a look at seogrove reinforced that immediate quality, content that does not require a slow careful read to demonstrate value but rewards one anyway is content with real depth and this site has produced work of that demanding depth class.
Liked everything about the experience, from the opening through to the closing notes, and a stop at theartofgrowth extended that into more pages, finding a site where the editorial vision shows through every choice rather than feeling random is an increasingly rare experience and one I am glad to have today during this particular reading session.
Even just sampling a few posts the consistency is what stands out, and a look at budgetfriendlypicks 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.
Honestly the simplicity of the explanation made the topic click for me in a way other writeups had not, and a look at dailytrendmarket continued that clarity into related areas, when a writer gets the level of explanation right the reader does the heavy lifting themselves and the post just enables it.

Found this via a link from another piece I was reading and the click was worth it and a stop at thebestvalue extended the value across more material the open web still rewards clicking through citations when the underlying writers care about each other work and this site clearly belongs to that network.
