No, this patch helps on performance - there is an improvement in numbers
between
http://git.postgresql.org/gitweb/?p=postgresql.git;a=commit;h=253de7e1eb9abbcf57e6c229a8a38abd6455c7de
and
http://git.postgresql.org/gitweb/?p=postgresql.git;a=commit;h=0e141c0fbb211bdd23783afa731e3eef95c9ad7a
but you will have to use a 9.5 pgbench to see it, especially with higher
client counts.
