[squid-users] -O2 vs -O3

Is there any significant advantage to compile Squid with -O3 instead of
-O2? (anyone saw improvements in the benchmarks?)
Or perhaps add other compile optimisations? (without hurting stability,
which is very important in this case)

My other compile parameters are: "-march=i686 -D_REENTRANT".
The target system will be a dual PIII Coppermine (256kB cache).
I'm compiling with gcc-2.96-112 on Linux Red Hat 7.3. I'm using the same
distribution on the target system.
