see the following web-site

PERFORMANCE:

I have compared the speed of the level 3 BLAS routines, using a benchmark program I found on
Netlib. I ran it using Dave Webers f2c+gcc compiled library, and also using g77 compiled static and
dynamic libraries. Here are the results, obtained on a 75MHz Pentium PC from Gateway2000.

So I see almost a factor two increase in performance! I also see the expected 5% penalty of the
shared libraries, coming from losing one register.
