In a recent stress test with our PostgreSQL-based cluster between two
machines
3 million transaction were performed with "pgbench -c 150 -t 20000 -s 200"
in about _ten hours_. The primary machine (desktop-level machine for
development)
used a real disk, the secondary used tmpfs as PGDATA. Say whatever you want
about my disk lying about flush, its 75MB/sec transfer rate transfer
rate is real.
So 5 million "real" transaction in 24 hours is not unrealistic.
