@Ben

As I understand that one runs on IE engine. Since IE is quite integrated into Windows it is considered hard to single out real memory usage for it.

hey have you guys tried the GreenBrowser? http://www.morequick.com/indexen.htm

It has been almost always using half of the memory of Firefox according to my experience

Glad to see you. :) You was missing longer than usual.

Hi Rarst,

I am here after a long time.

Nice autoit script.

Will test on my Lappy.

[...] Speaking of speed also check out Rarst’s Firefox and Opera Test. [...]

@Jonny

That would be visual but not too correct of methodic. Process Explorer can be quite resource hungry itself and without logging capabilities unfit as emasurement tool.

It’s not a problem to log CPU usage, it’s problem to do it rapidly, accurately and without influencing system performance which might shift the very CPU usage being measured.

I’m not sure exactly how you’re script works but couldn’t you use Sysinternals / Microsofts Process Explorer to monitor cpu over the runs?

@Chocobito

CPU consumption is interesting but harder to measure correctly because it comes in short spikes. It would require much higher poll rate (three seconds won’t do), that may itself affect OS.

There is also factor of storage that may affect CPU usage. Or so I think.

I will try to add CPU monitoring to script (probably on weekend) and will see if it makes enough sense to update post. Thanks for suggestion and sharing your experience!

I try my self to make a very raw test for probe memory consuming in Opera 10B and Firefox 3, actually I open 15 very content loaded web page at once, wait to fully load and see how much memory consume each browser, as the result Opera round to 170 to 190 MB, Firefox round to 90 to 120 MB. Opera consume more memory that Firefox but in all the test process, Firefox was very much CPU time consuming, reaching 90% of CPU, Opera only sometimes reach 50% and almost all the time was low 20% of CPU time. Rarst, maybe you can make a CPU consume comparison among browser and share your result. Sorry for my terrible English. Take care.
