Could this be a berkeley db issue?

I posted earlier today about a performance issue I'm seeing with
cyrus-imap 2.2.4 (and 2.2.5, I attempted an upgrade)... A basic summary
from before:
- RedHat Enterprise Server 3.0
- Upgrading from Redhat 7.3
- Cyrus 2.2.5
- Upgrading from Cyrus 2.0.16
- Pam auth through sasl, authenticating against a mysql db
- Running SMP on a dual processor machine. RedHat Enterprise Server comes
with libdb-4.1 installed
The server seems to function fine, just slowly...
I've run local imtest -z runs on the server, and I've seen finishing
results on the order of anywhere from 40-60 seconds.
Running the same test on a RH 8 server , running cyrus-imap 2.1.something,
with similar authentication routines took 3 seconds... so I'm feeling
pretty confident that the auth method is not slowing things down to this
extent.
I read some not-so-clear comments in the archives that mentioned very
bizarre libdb-4 issues, with redhat distributed libdb-4 (or maybe I'm
remembering incorrectly), especially with threading issues.
Seems threading issues could cause really slow performance... Does this
sound like I might be on the same track?
Any other ideas that I might try? Unfortunately, the server got placed
into production before we noticed the performance problem!
