Hi,
I am running relatively complex queries to analyse a dataset. I have
query execution times of around half an hour with version 5.27 I tried
both version 5.33 and 5.34, and experienced the following:
The first few queries ar run faster than with version 5.27, but after a
while a query remain hanging. Mysqld is totally using one of the
processors. The strange thing is that the load moves from one processor
to the other. But this might be some Windows weirdness. I know about
the undecideability of the stopping problem, but I find the increase of
the execution time from approx 30 minutes to more than 16 hours pretty
unprobable.
Anybody experienced similar things with these versions? Any idea how to
debug/circumvent this problem? Beta patches? Anyone? The speed
increase I experienced with the first few queries would be nice to have.
