JSIO Performance Results

Posted on by

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:

  13. Reading this prompted a small redirection in something I was working on and a stop at forwardmotiondefined extended that redirecting influence content that affects my actual work rather than just my thinking has the highest practical impact and this site is providing that level of influence for me at a sustainable rate apparently.

  14. Thanks for not padding this with the usual filler intros and outros that every other blog seems to require and a quick visit to chrishallforjudge 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.

  27. Thanks , I have recently been searching for information about this subject for ages and yours is the best I’ve discovered till now. But, what about the bottom line? Are you sure about the source?

Loved the writing voice here friendly without being fake and confident without being arrogant and a stop at forwardmotiondefined carried the same tone forward the kind of personality that makes a reader feel welcome rather than lectured at which is a balance plenty of writers struggle to find no matter how long they have been at it.

  32. Now understanding why someone recommended this site to me a while back and a stop at chrishallforjudge explained the recommendation sometimes recommendations make sense only after experience and this site has finally clicked into place as the kind of resource I now understand was being recommended for sound editorial reasons by my friend.
