ATLAS Pentium III Timings
From user mail, it seems that few people appreciate that there is a
fairly significant gap between stable and developer performance for
a variety of machines.
This graph compares the performance of ATLAS 3.5.6 and 3.4.1 using
double precision matrix multiply and LU factorization.

This graph gives the same information for single precision real:

Note that the 3.5.6 install used a CacheEdge setting of
249856. This machine (my laptop) has a 256K L2 cache.
I no longer have access to MKL to compare against. Last time I did was
