No real reason, tried various different settings but to no real advantage.
Now I have:
Filesystem size used avail capacity Mounted on swap 19G 7.7G 11G 42% /tmp
# grep cache DB_CONFIG set_cachesize 8 0 1
# time /usr/local/BerkeleyDB.4.8/bin/db_stat -d id2entry.bdb real 6m6.099s
# time cp id2entry.bdb /dev/null real 0m0.040s (It's not on disk)
Now repeat the db_stat call and see how long it takes the 2nd time.
