        You could try compiling your kernel and C library with pentium
GCC.  It's at www.goof.com/pcg and is stable at all optimization levels,
such as CFLAGS=-O6.
        Also try kernel 2.1, and hdparm for IDE drives.
        If you dont have a pentium, try the egcs enhanced gcc compiler,
which is what pgcc is based on. 
        I've seen 200% improvements with the unix Byte benchmark.  Quake
even has higher fps with a pentium-optimized math library.
