Could you provide a bit more details about how you ran the benchmark? The
reason I am asking is that ~330 TPS is pretty slow for -c20. Even on spinning
rust and using the default settings, I get considerably higher results.
Oh - I do get results closer to yours if I use pgbench scale 1, causing a lot
of row level contention. What scale did you use?
I use default scale of 1.
And run the command sequence:
$pgbench -i bench
$sleep 1
$pgbench -c20 -T10 -j8
in a loop to get similar initial conditions for every "pgbench -c20 -T10 -j8"
run.
Thanks for your interest!
With the best wishes,
