Probably not as much as the hype suggests. But I think it is noticeable
(5% to 10% is the figure touted for Pentium optimized gcc versus i386
gcc).
In some cases you can use special instructions (MMX, SIMD, etc.)
to get big speed improvements for specialized applications (image
processing, SETI@Home). But in those cases the standard i386 build
might contain all the possible assembler-optimized routines for
different i386-compatible processors and choose between them at run
time.
Personally, I am thinking about rebuilding the Mandrake packages for
386 and 486 processors, so I'd like the installer to cope with that.
