firefox perfomance

about:buildconfig

Compiler     Version     Compiler flags
gcc     gcc version 4.6.0 20110415 (prerelease) (GCC)     -Wall -W -Wno-unused -Wpointer-arith -Wcast-align -W -fno-strict-aliasing -pthread -pipe -DNDEBUG -DTRIMMED -Os -freorder-blocks -fomit-frame-pointer

why only -Os? why not -O2 or even -O3? in other distros (such as SUSE for example) firefox much more optimized and much more faster

That is the Mozilla default.  Certian sections of the code a re compiled with more optimization as they see fit.

You can always compile on your own, but I don't think you will get more than 5% improvement.

Re: firefox perfomance

Cheer up, our woes will probably be over soon.

Read this on /. yesterday:

Also if you impatient enough, then try this"

I tried firefox-pgo with the 3.6 series. It did feel snappier, but it wasn't worth the 2 hour compile time, that my poor and hot-headed (read get very hot, very fast) p4 had to go through.
