BerkeleyDB transaction performance, like any other ACID database, is limited to disk performance (unless you have a non volatile ram, of course). Using ext2 and such, you are happy if you get 30-50 transactions per second. Using nice Solaris ZFS, I do a transaction per rotation; that is, 120 transactions per second with a consumer level 7200RPM disk.
PS: Until Oracle takeover, BerkeleyDB was the heart of MySQL transactional engine. I don't like mysql, but not for its use of BerkeleyDB :-).
