Comments on: Windows Low Fragmentation Heap builds http://pavlovdotnet.wordpress.com/2007/11/13/windows-low-fragmentation-heap-builds/ Ramblings from the mind of Stuart Parmenter Thu, 20 May 2010 00:16:37 +0000 hourly 1 http://wordpress.com/ By: Steve Chapel http://pavlovdotnet.wordpress.com/2007/11/13/windows-low-fragmentation-heap-builds/#comment-445 Fri, 16 Nov 2007 18:24:07 +0000 http://pavlovdotnet.wordpress.com/2007/11/13/windows-low-fragmentation-heap-builds/#comment-445 After running Pandora Radio for over an hour (until it asked me to register) memory use hit a high of 118 MB. After closing all tabs but one open to the default home page, memory use is down to 50 MB. Long-running Flash apps don’t seem to be a problem for the regular Firefox 3 nightly builds, at least on Windows XP and with the latest Flash Player.

Could you list those pages that quickly ran through memory? If I can reproduce a problem, I’ll file a bug report. By Pandora, do you mean pandora.com Pandora Radio? If so, I’m trying that now to see if I can reproduce a memory problem with the latest Firefox 3 nightly and Shockwave Flash 9.0 r47 on Windows XP.

I did try testing with 3.0a8, just a couple (10) pages quickly ran memory up to ~190MB and rising. Long-running Flash apps (Pandora, etc) seem to really eat up memory.

This special build (again, I don’t have a regular 3.0b1 build) consistently keeps memory around 120-130MB with the same set of pages, even with Pandora running.

The regular Firefox 3 trunk build uses 122 MB after running the test and closing all but one tab. The special Firefox 3 beta 1 build uses 131 MB after exactly the same test. My opinion is that any perceived decrease in memory use is a placebo effect. I’ll post more results in this MozillaZine thread: http://forums.mozillazine.org/viewtopic.php?t=429446

I’ve got my binary component for heap dumping almost done. The code is written just having some packaging issues. Will get it out by tomorrow at the latest.

Closing pages even decreases memory use!

I haven’t been able to test Firebug, which I’m sure drives up memory use in normal Firefox builds. Firebug 1.1 beta works with 3.0a8, but I can’t get it to activate in this build.

Pete.
