firefox-16.0.1_1,1 builds, but doesn't work

Probably, although I have not looked. All I can say is that I never noticed any performance improvement from these. What I did notice was that turning on PGO took a very long time to compile the port and used lots of swap. Not that I've noticed, although I have not tried either since deciding they were a waste of time. OPTIMIZED_CFLAGS might be worth trying again, now that it has been eliminated as a source of this problem.

This is far from objective, but on old hardware (Pentium M 1500MHz, 1GB of RAM, AMD/ATI Mobility Radeon 7500) I think I see some gains. Scrolling seems smoother and faster and things just seems a bit snappier. This is with both PGO and OPTIMIZED_CFLAGS turned on versus both turned off.
