What is the maximum number of insert postgresql achieved so far?I don't have hard numbers handy, and I know I don't have the fastest hardware out there, but for bulk loads of narrow tables we typically see tens of thousands of rows per second. Of course that's with "running with scissors" settings. We turn off archiving, autovacuum, fsync, full_page_writes, and synchronous_commit; and COPY rows within the same transaction which creates the table, before creating any indexes. Then we build the indexes, VACUUM FREEZE ANALYZE, and change back to a configuration which actually preserves the data on a crash. From memory, I would say on our larger servers we've probably seen a max of something on the order of 50,000 rows per second on relatively narrow tables, without factoring the index build and vacuum times.
Are there any numbers around for OLTP like systems? Would be nice to know what is possible with PostgreSQL in this case.
