This may be a little small. I prefer to fully cache my DB.

So with 300,000 users, your caches look fine.  I would definitely recommend 
using an SHM key if you are going to stick with using BDB.  I personally 
prefer using MDB with current RE24 these days. It is magnitudes faster than 
BDB in all aspects if you enable writemap.
