I've been using pgcc compiled kernel, optimized for K6 for quite a while,
also I compile my new software for K6, I also tried -march=pentiumpro, and
-mpentiumpro, stuff seemed to work fine, but I think -march=amdk6
-mcpu=amdk6 works better. 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).
