When 1 client connected postgres do 180 execution per second
This is suspiciously close to 10.000 executions per minute. You got 10k RPM disks ? How's your IO system setup ?Try setting synchronous_commit to OFF in postgresql.conf and see if that changes the results. That'll give useful information.
