[pgpool-hackers: 3233] Re: pgbench: Flamegraph

Hi Jesper,

Here's an another attempt to enhance Pgpool-II performance in
extended query + streaming replication case. The idea is to minimize
the necessity to call pool_flush(), which in turn calls write(2) to
the frontend socket. Attached is the patch and quick result of
pgbench. In pgbench -S case, I got up to 10.6% improvement over stock
master branch HEAD.

Best regards,
