Everyone have probably seen the benchmarks about the poor performance of Firefox on Linux compared to Windows. Apparently even Wine+Firefox beats native firefox (actually I tried it and its true).
Some say it is because Win FFX is compiled with PGO ( profile-guided optimization) and without in most Linux distros.
So, my question - can I request that FFX be compiled with PGO? or is there some technical reason its not done so already?
So doing it automated isn't that easy since to create the profile you have to exercise stuff in a running Firefox (at least on Linux). I'm open for input how that could be done in a packaging environment.
