Hi,

Would be worth knowing how much of the time pgbench is 100% CPU
utilized, and how much of the time it is basically waiting for server
side queries and largely idle.
If it's close to 100% busy for a significant part of that time, it'd be
useful to get a perf profile. If it's largely queries to the server that
are the issue, logging those would be relevant.
Greetings,
Andres Freund
