Thanks for the interest.

The new MTIMES routine in Jacket 1.4 has improved sigificantly since these benchmarks of the Release Candidate were taken. 
See the <strong><a href="http://wiki.accelereyes.com/wiki/index.php/MTIMES_Benchmarks_(Jacket_1.4)" rel="nofollow">MTIMES Benchmarks</a></strong> wiki for an up-to-date listing
of Jacket's performance. 
Dynamically adjusting for optimal performance automatically is the next area of focus for Jacket's MTIMES, scheduled to be included in the next release.
