Also, maybe you already know this, but gzip, compiled with -Os option is significantly slower than gzip compiled without size optimization for K6. Also I noted that gzip compiled for pentium is slower that gzip compiled for amdk6 on amd machine, this kinda shows that amdk6 optimization actually works quite nicely. I use Stampede distribution, so everything is compiled for pentium, including Glibc 2.1, and the software that I download is getting optimized for K6. Seems to be quite stable. It would be interesting benchmarking AMD K6 and Cyrix MII machines with Linux kernels/software pgcc-optimized. Cyrix is so much cheaper, but it's FPU sucks really bad. Cyrix File/Print server should do approximately as good as AMD, or a little worse (66 MHz bus).
