It's really handy to find a stable, sustainable throughput on master at which a replica can keep up. PostgreSQL is about more than raw TPS. Users care about latency. Things we change affect latency. New index tricks like batching updates; sync commit changes for standby consistency, etc. That's not a reason to throw anything and everything into pgbench. But there's value to more than measuring raw tps. Also, I'm not the one doing the work. -- Craig Ringer http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Training & Services
