OK, so I've done what I can.
To find out you might have to look at the LAPACK functions you are using and compare them against the ones provided by ATLAS.
Well, I'm testing using LinearAlgebra.solve_linear_equations() from Numeric (and numarray). The reason I'm wondering is that on my last machine, a 1ghz PIII laptop running Gentoo, using the Gentoo provided atlas/lapack, I got a 6-7 times speed up over lapack_lite. On my new machine, a 2GHz Pentium M laptop running FC4, I got about a 2 times speed-up, which is nice, but not nearly as impressive. Another possible issue is that I used pre-complied binaries form the atlas site, which are a bit old, maybe I should compile myself.
