Check my post a few months ago on optimzing linux binaries, and optimzing the game on a linux box.. You can actually add quite a few more inline optimizations when compiling. I also included some tips on recompiling your mysql server for better performance.
Another big one is that the compile arch. flag is set for i386 in the makefile. This is the most compatible, but is missing ALOT of newer architecture hooks.
In addition. Consider installing and compiling with gcc3.1, one, you can use the new CPU specific flags (march=athlon, athlon-mp, athlon-xp,etc) , PLUS, 3.1 binaries are an average of 15% faster in performance. (still not as good as intels compiler, but gcc is getting there).

This has been a few months back, so there are better optimizations available, especially with the new gcc . (Its been a bit buggy, but I HIGHLY recommend it. I've recompiled a good deal of my system with it and Im impressed by the differences. Also, if your into performance, go with the gentoo distro, it will compile everything from source with current optimization flags (problem with most linux distro's these days is theyre compiled using i386 flags for maximum portability, and no optimization). The portage system makes it EXTREMELY easy to rebuild and upgrade packages.
Just my findings, but I can tell you they made a BIG difference on my systems.
And of course, YMMV.
Good luck!
