I have *not* migrated to 3.2.0 yet. But on my test hosts, version 3.2.0 seems to be noticiably slower than the current version we are running. This is a qualitative measure only--if I get a chance I will try to post something quantitaive later. > >By "large number" I'm talking about a couple hundred, which realistically >isn't a very large number.
