The page on installing Ubuntu on a T23 includes tips for monitoring and managing the processor speed settings.

GCC Optimization Flags

You should use the following if you have a Mobile Pentium III-M:

-Os -march=pentium3m -fomit-frame-pointer -pipe

"-Os" means optimise for size. "-O2" is usually the default and is probably more prefferable. If you're feeling brave you could try using "-O3", but many programs fail to compile with this (attempting to compile binutils, gcc or any other core tools with "-O3" is not recommended)
