Firefox memory weirdness

Submitted by dag on Thu, 2008/12/25 - 00:40

Dear Interweb, please explain me this:

If I have 80 tabs open in Firefox and I have 2GB of physical memory and I then restart my browser. It eats up 1GB easily and then slowly grows until it hits 1.5GB of memory (almost all available).

If I have the same 80 tabs open in Firefox and I add 2Gb of physical memory (total being 4GB) to exactly the same machine and I then restart that same browser. It eats up only 300MB of memory and never really grows much beyond 400MB.

What am I missing here ?

Tested on a CentOS 5.2 with Firefox 3.0.5.
