Default Benefit to tweaking CFLAGS of NVidia driver?

I notice that when the NVidia driver compiles the driver for my system the compiler options *seem* to be sub-optimal.

The flags used are -O with an implied i386 target CPU. That seems pretty conservative. Given that my actual CPU is a Pentium4, would there be any benefit to playing with the compiler optimizations used to build the driver for my system?

Thanks.

If you're using Linux 2.6, the CFLAGS are inherited from KBUILD (the Linux kernel build system); it is not recommended that you change these flags (there's nothing to be gained in terms of performance).
