I did, thanks for reposting.
Yes, the numbers look good ~30% speedup in some of the cases
I inspected.
I'm happy with the results. If nobody objects I'd say check
in your patches on Friday.
What we really need now is a comparison script to collate
and compare two sets of results. It was annoying to look at
the result data manually :-(
Cheers,
Carlos.
