(It would be > easier to recommend alternate approaches with more details.) I've already split it up into 11 functions, which are being managed through Perl with ANALYZE statements between. Breaking it down further would be really unmanageable. Not to be mean or anything (after all, I just joined pgsql-advocacy), I'm getting *much* worse performance on large data transformations from PostgreSQL 7.2.1, than I get from SQL Server 7.0 on inferior hardware (at least, except where SQL Server 7.0 crashes). I really am determined to prove that it's because I've misconfigured it, and I thank all of you for your help in doing so. PGBench Results: transaction type: TPC-B (sort of) scaling factor: 10 number of clients: 100 number of transactions per client: 10 number of transactions actually processed: 1000/1000 tps = 93.206356(including connections establishing) tps = 103.237007(excluding connections establishing) Of course, I don't have much to compare these to, so I don't know if that's good or bad. -Josh Berkus
