Not that I know of.  And since an optimized BLAS almost always means
machine and compiler dependent code (perhaps written in assembly
language), and because machines and compilers keep changing, looking
for hand-coded BLAS is probably not a very good long-term solution.

There may be some hope for a good solution to this problem though, in
the form of the ATLAS project:  http://www.netlib.org/atlas/index.html.
ATLAS may eventually provide a generic way to optimize the blas for
any machine and compiler.  I don't think it is quite ready yet, but
perhaps we can eventually use it to get a little bit better
performance on all the systems where Octave can run.
