On a particular system, loading 1 million rows (100 bytes, nothing fancy) into PostgreSQL one transaction at a time takes about 90 minutes. Doing the same in MySQL/InnoDB takes about 3 minutes. InnoDB is supposed to have a similar level of functionality as far as the storage manager is concerned, so I'm puzzled about how this can be. Does anyone know whether InnoDB is taking some kind of questionable shortcuts it doesn't tell me about? The client interface is DBI. This particular test is supposed to simulate a lot of transactions happening in a short time, so turning off autocommit is not relevant.
As you might imagine, it's hard to argue when the customer sees these kinds of numbers. So I'd take any FUD I can send back at them. :) -- Peter Eisentraut http://developer.postgresql.org/~petere/ ---------------------------(end of broadcast)--------------------------- TIP 3: if posting/reading through Usenet, please send an appropriate subscribe-nomail command to [EMAIL PROTECTED] so that your message can get through to the mailing list cleanly
