Andrew said I should solicit opinions as to what parameters to use. A

10, 5 users, and 100 transactions.

100 transactions seems barely enough to get through startup transients.
Maybe 1000 would be good.


Scale factor 10 produces an accounts table of about 130 Mb. Given that most HW these days has at least 1G of ram, this probably means not much retrieval IO is tested (only checkpoint and wal fsync). Do we want to try 100 or even 200? (or recommend scale factor such that size > ram)?
