Sorry for the delays on this that machine actually died recently and had to
be rebuit before I could do any more tests.

Are you very interested in the comparison? I could fake a load of the
non-transactioned tempoary table queries if you are really interested.
I also noted we sometimes get a load of temporary tables left lying around
that look "global" and we have to drop by hand.
After rebuilding the machine I did a dump from the other machine and
inserted on the new machine (schema, data and all) and the new machine is
VERY slow at queries; taking 4 seconds at 100% cpu at times instead of
0.2-0.5 seconds or so.
Yet if I copy over the binary files when the DB's are stopped the new
machine is very fast at queries.
Could this be because the new machine started on 7.2.1 with a different
optimiser and so never generated query stats the the old box did while it
was still on 7.2 ?
