RE: [squid-users] Which Compiler for Squid on Linux x86?

What about something like PGCC? For x686 and Athlon, I hear that a lot of
the optimizations in pgcc are comparable in similar improvements in many
cases to Intel's compiler.

I forgot to mention that for gcc I did manually add the -march=i686
