Hello - I have a HTML page which I've modified to include some JavaScript. I'd like to do some sort of metrics to determine how much 'longer' this page may or may not take. 

Technically, I'm taking 72k of HTML, and using externally cached JS files, one with 20k of data, and basically 'creating' the 72k of html and then innerHTMLing it.  Doing so will enable caching across all of our pages, vs putting that load on every page for the site.

Does anyone know of some sort of freeware tool which is able to slow down an app, or even the machine (to like 500 mhz single proc) so that I can see the time the page with this new javascript code?

Don't touch that mustard. It's Jerry and Bills.
Maybe just throw a couple of <script> tags in your code with some timers to help kill a few seconds...

First off, why did you mention Netscape?

It doesn't exist anymore, the engine is now known as Gecko, the "Netscape" browser (version 8) is just a rebranded Firefox distribution, nothing special.

Technically, both Mozilla Javascript implementations were created by Netscape.  Looking at the project page, it looks like JS never had the major rewrite that the layout engine did with NewLayout/Gecko.

Actually Firefox is rebranded Mozilla, which is rebranded Netscape.. and updated a little. They all use the same engine.

Anyway, as for the question... http://www.cpukiller.com/ mght help you Smiley

Bah, details details.  Its habit and comes out as netscape before I correct and say Firefox.  Regardless, the question was how to compare javascript. So as far as it matters, maybe I DID mean netscape. The actual browser is irrelevant, I could have said Safari/Khtml. 

Timers will not work since the machines around me are too fast, I almost want more of a profiler to see what cycles are being chewed up in each browser, but I'll just stopwatch time it on a slow machine.

Thanks.
