We've been using -O3 -mpentiumpro for Pentium processors for a long time and have seen no problems with it.

GCC 3.x has been working also without problems, but we don't have that much experience of it yet. Currently we are using 2.95.3 for most things. > Any one? > > Thanks > > Daniel Regards, - Jani Ps. Why are you compiling MySQL on your own (just curious) ? If you are only looking for optimization, I would strongly recommend you to download one of our binaries, because they are very highly optimized, and the risk of getting an unfunctioning binary (in high loads for example) is low. If you need to compile one by yourself, please check the MySQL manual for hints about compiling options for your platform.
