From 2d6c0f10ef4f34d757e49a9815c22045d8ba6980 Mon Sep 17 00:00:00 2001 From: Noah Misch Date: Sat, 5 Oct 2013 17:33:38 -0400 Subject: pgbench: Elaborate latency reporting. Isolate transaction latency (elapsed time between submitting first command and receiving response to last command) from client-side delays pertaining to the --rate schedule. Under --rate, report schedule lag as defined in the documentation. Report latency standard deviation whenever we collect the measurements to do so. All of these changes affect --progress messages and the final report.
