I should have mentioned that my timings were done on a 900 MHz Athlon
processor running Debian GNU/Linux 2.3. The system has 768 MB of
Apparently the optimizations used in ATLAS are particularly effective
on the Athlon. Other processors may not show such dramatic speed
I did not compile ATLAS for this machine. I used the Debian atlas2
package which, according to the documentation, was optimized for a
Pentium II (350 MHz). There may be some modest gains achieved by
recompiling. I tried to recompile from the sources but the Debian
package build failed and it is too late at night to start working on
why it failed.
