Without patch we have 417523 TPS and with patch 965821 TPS for big x86 server.

Impressive!

I've run this on a single CPU server and don't see any speedup, so I assume I'm not getting enough contention.
As soon as our 4 socket machine is free I'll try a pgbench run with that.

Just for fun, what's the results if you use -M prepared ?
