Thanks for running tests! >While I saw an improvement for the 'synchronous_commit = on' case - >there is a small regression for 'off', using -M prepared + Unix Domain >Socket. If that is something that should be considered right now. What tests where you running, in which order? I presume it's a read/write pgbench? What scale, shared buffers? I right now can't see any reason sc on/off should be relevant for the patch. Could it be an artifact of the order you ran tests in? Did you initdb between tests? Pgbench -i? Restart the database?
