Thanks for testing. Network (or communication between pgbench and postgres) seems to be a bottleneck on your machine. > Two questions here: > > 1) How will be this behavior in a syncrep environment?

We already run the collector during warm-standby, so profiling would be also available on log-shipping slaves. > 2) I couldn't find a clear way to disable it.
