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.
