From 3ca110f8dc6a552e951074faaca3a11ce65e40f3 Mon Sep 17 00:00:00 2001 From: Russell Bryant Date: Thu, 9 Jan 2014 17:28:11 -0500 Subject: [PATCH] Cut tempest concurrency in half While a group of us were investigating the top gate bugs today, at least half of them are due to performance issues where nova isn't able to keep up. This change is to test the theory that dialing back the test load will increase reliability of the gate. We also have a lot of good data and ideas on how we can improve nova performance (in particular, nova-network). Hopefully we could turn this back up in the future.
