Hi,
This Benchmark test has had me intrigued for some time, especially in 
Linux systems where system libraries change continuously. And I was 
especially amused when my little 2.0GHz Pentium M laptop (Debian 
Linux kernel 2.6.12) outdid a Redhat 9 Pentium4 3.2GHz and the Athlon 64 
3200+ (Suse Linux) when it came to Transposing matrices. I guess thats 
where the buck stopped, because it was thoroughly thrashed on all other 
accounts.

Cheers
Yas
