From f16d4a241594bb198e1abedb5e43977ef796370a Mon Sep 17 00:00:00 2001 From: Heikki Linnakangas Date: Wed, 21 Sep 2016 13:14:48 +0300 Subject: [PATCH] Fix pgbench's calculation of average latency, when -T is not used. If the test duration was given in # of transactions (-t or no option), rather as a duration (-T), the latency average was always printed as 0. It has been broken ever since the display of latency average was added, in 9.4.
