x?lutst is typically better then x?lutstF for small problems, and very
large problems.  If you have a good level 2 BLAS, it may not be better
for small.  Asymtotically lutst should win, but by how much again depends
on the platform.  Have you tried running large problems, say something like:
   ./xdlutst -T 0 -N 1200 3000 200
