However, there is a problem that I can't resolve by myself. Principal component analysis runs really slowly (three times less than on a equivalent octave installation on a Debian runnng on a PIV 3.2 GHz). Things are worst when octave was compiling linking ATLAS libraries instead of vecLib ones.

Have you any idea ?

A starting point could be this document: GS_Performance/index.html
