We use BDB with a particularly large DB (close to 300,000 people with 20+ 
attributes each), and have no performance problems to speak of.  Our 
systems are heavily utilized 24/7.  There are some basic configuration 
pieces to BDB that can help improve performance.  I would be curious to 
know if your slowdowns happen to coincide with write activity.  Also, have 
you looked at your BDB stats?  Perhaps you have not allocated a large 
enough cache.

OS: Solaris 8
LDAP: 2.1.17
DB: Berkeley DB 4.1.12
Hardware: SunFire v120 650MHz with 4GB RAM
