A few percents might as well be due not to the code itself, but to code and data alignment, which have greater effect on Pentium CPUs. Make sure you are using the latest Binutils version, which aligns code and data in the optimal way. Also, GCC 2.95.2 emits smart alignment directives, as per Intel's recommendations, which are supported only by Binutils 2.9.x and later. So by using the latest compiler and Binutils you will have the best combination as far as alignment is concerned.
