Use ruby-1.9 it is faster.
Compile with gcc-4.1
Optimize

CC=gcc-4.1 CFLAGS='-march=pentium4 -O3 -fomit-frame-pointer' CPP=cpp-4.1 \
CXXFLAGS='-march=pentium4 -O3 -fomit-frame-pointer' 'CXX=g++-4.1' \
./configure
make


Warning, this may be hazardous for your health, but it works for me.

ps. Anyone worked out how to use gcc profile feedback to build a faster 
ruby yet?
