Recent jQuery Performance Updates

Now folks, you know, I was always saying "there is nothing like a smell of good statistics in the morning!". Now lets take a look at that 2x speed up claimed over here.

I'm using my Shakker util to perform the tests. You can also read why I don't use Taskspeed anymore.

So to the tests. Lets take a look at the Firefox test



Yea, kind a bit of speed up at claimed `bind`, `html` and `remove` methods, certainly not 2x, and note how it actually got slower at 1.4.1 and then gets back to almost the same values as 1.4.0.

Now lets take a look at the same thing at Safari



A different scale, the same picture, it's getting slower from 1.4.0 to 1.4.1 and then gets back to almost the same values at 1.4.2. No 2x speed up between 1.4.2 and 1.4.1, more of that almost no speed up at all and certainly no 3x speed up agains 1.3.2.

Well, lets get further and take a look at the test in another fine browser, Chrome.



The same exact picture with the `bind`, `html` and `remove` methods, got slower on 1.4.1 and to the same value at 1.4.2.

Now you should get back to that release notes page and ask yourself "why there are no results for version 1.4.0?".

Yup, because there is no speed up, they merely fixed their own fuckups in 1.4.1 and now present it as 2x speed boost.
Awesome! :)
