Here were my results today using that website, everyone can run their own tests, 110919 if anyone cares: 132 120 229 426 494 152 13815 142

DOMAssistant 2.8(132); jQuery 1.4.2(120); Prototype 1.6.1(229); Mootools 1.2.4(426); ExJS Core 3.1(494); Dojo 1.4.1(152); YUI 2.8.0(13815); YUI 3.0.0(142) ~ as you can see version updates, the new jQuery is impressive.

jQuery 1.4.2 was the fastest, followed by YUL 3.0.0 and Dojo 1.4.1. On this system I was running FireFox 3.6.11 on Ubuntu 10.04 w/ an older Kernel 2.6.32.xx but that should not matter…FYI. I wonder how my Linux Mint or Debian boxes will do? What will I discover when I install Arch on a small netbook with only 512 MB of RAM?

The test in this post makes me want to check out Dojo and Safari specifically.

It appears that adoption/news of the jQuery framework is significantly increasing and perhaps your comparison hints at why:

I did not include Dojo or YUI in the Google -dance listing above because of Karate references (Dojo) and the Japanese singer (YUI) which greatly skew the results. I know its not scientific, so please do not flame, I just find it interesting.

Comparison of PHP Frameworks: (Interesting, not scientific):

It will be interesting to see how jQuery, and Dojo specifically interface with various PHP Frameworks, my current focus. Are they easy to integrate with each PHP framework, etc… I expect few issues based on past experience.

I ignored the Linux v Windows OS comparison, as should others IMO, over the years we have observed many tests invalidated based on optimizations automatically turned ON in either IE or Windows that skew the results….some sleuthing would need to be done to highlight them and apply the equivalent optimizations on the Linux system (…in Linux all the optimizations will exist, whatever they are) in order to get an accurate comparison from an OS perspective. [obviously not the primary focus here] Rarely is a Linux system slower than Windows. Start dropping memory to lower levels (I run one Linux “server” with only 256MB for coding/testing in lower memory conditions, ie Linux handhelds) the new windows would not be an option at 512MB and below, perhaps not even at 1GB of RAM. Even Linux w/ WINE usually runs faster for the one or two MS games that will never be optimized for Linux users. With Linux, since the OS requires such a small memory footprint, there is more memory available for applications and data, as it should be.

I agree with posters above, this article helped me decide which JavaScript framework(s) to focus on. After all in the long run, we all want our websites to perform and keep performing as they scale! While the latest version of jQuery really performs, I intend to keep my eye on DoJo. Thank you!
