Re: [Dynapi-Dev] My JS Optimization Site

[Daniel A. <dan...@ne...>]

Hi,

Nice site, Jeff. Some interesting tricks there I hadn't thought about. I
liked the Duff's Device code, although I noticed it can be improved.
Here's a version of the code which doesn't have the case stuff in the
main loop but can still do a custom number of iterations. On my computer
I get these results in NS4.7 and similar results in IE5:

Ordinary: 601 ms
Duff's: 431 ms
Duff's Optimized: 250 ms

Of course, you'll only get a noticable speed improvement on this kind of
optimization when you're doing a huge amount of iterations with a loop
body which doesn't consume much time. And it's horribly unreadable code.

Cheers,

Daniel
