My olcDB values are listed below (minus the olcDbConfig entries). I'm not sure if you need the indexes but I've left them in anyway:
olcDbCacheFree: 1 olcDbCacheSize: 400000 olcDbIDLcacheSize: 1200000
set_cachesize 4 0 1
This may be a little small. I prefer to fully cache my DB.
I'm not using an SHM key (should I be?).
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.
