And your checkpoint settings?
The performance you're seeing is pretty bad for a server that has more
than 40GB of memory. I can get far superior performance on the same
benchmark with a relatively inexpensive workstation, at least on the
master branch.
Try these for a start if you're using default checkpoint settings, as
I suspect you are:
checkpoint_timeout=5min
min_wal_size=10GB
max_wal_size=40GB
wal_compression=on
backend_flush_after=0
checkpoint_flush_after=256kB
checkpoint_completion_target=0.9
