Re: [AMaViS-user] severe performance degredation by amavisd 2.6.4 under load

I saw a suggestion from Matt Reimer back in April regarding ditching db41
for db42 to resolve a strange performance issue with Amavisd on FreeBSD 8.
Yeah. That was it. I ditched db41 for db42 and wow what a difference.
That box is now doing over 16k messages per hour (was maxing around 6k
before), has no problem with 25 max_servers (several of those sit idle so
I wonder just how high I could push the messages per hour if I configured
the load balancing to send that much of a load to this box)....AND this is
while I'm doing a make buildworld. Nice.

Matt Reimer you rock.
Marc, perhaps this needs to be mentioned in the release notes or
something? It definitely solved a huge problem that I've been chasing all
day now.
Thanks,
Andy
