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 :-). - -- Jesus Cea Avion _/_/ _/_/_/ _/_/_/ jcea@argo.es http://www.argo.es/~jcea/ _/_/ _/_/ _/_/ _/_/ _/_/ jabber / xmpp:jcea@jabber.org _/_/ _/_/ _/_/_/_/_/ ~ _/_/ _/_/ _/_/ _/_/ _/_/ "Things are not so easy" _/_/ _/_/ _/_/ _/_/ _/_/ _/_/ "My name is Dump, Core Dump" _/_/_/ _/_/_/ _/_/ _/_/ "El amor es poner tu felicidad en la felicidad de otro" - Leibniz -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iQCVAwUBR83ia5lgi5GaxT1NAQJ5NwP/bIBXEDO3158cnAQhfz2TH70aPK7T3YDg SD3FQMoALNSKb5JP8MsMicRB9JcQUdmznEmi3L2C5TrhvLv/Rb2GBZVyJqqGrFn/ ceBYwIzbV2utniWkk7J7bUWisutZQp72//6CNZFNqM6kPA/MLSngm732V1ZX6JRC vzhsWQhO9i8= =2AQ8 -----END PGP SIGNATURE-----
