I re-ran the series of performance tests that I published a few days ago,
with  0.6beta1 and the new C extension enabled. The results are at:

There are some significant improvements listed particularly in areas of
form handling. As far as I can tell my environment is virtually identical
to when I ran the last series of tests.

Does the change in results seem reasonable given the changes in this release?
