I repeated David's original tests not terribly rigorously[*] and got these numbers:
* Unpatched: 72.396196 * 0001 : 77.279404 * 0001+0002: 20409.415094 * 0002: 816.606613 * control : 22969.140596 (insertion into unpartitioned table) So while this patch by itself gives a pretty lame increase in tps, it removes bottlenecks that will appear once we change the locking scheme. [*] On my laptop, running each test only once for 60s. -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
