I presume that batch file was executed linearly -- no parallelism? You're actually testing one of PostgreSQL's shortcomings. PostgreSQL (in my experience) does much better in such comparisons with a parallel load -- multiple connections executing varied work (short selects, complex selects, inserts, updates, deletes). Anyway, just a tip that you will want to test your actual load. If you do batch work with a single thread, what you have is fine. But if you have a website with tens or hundreds of simultaneous connections then your non-parallel testing will not reflect that work load. ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
