The gate jobs are run in parallel -- so gate-nova-python27 is started at the same time as gate-tempest-devstack-vm, assuming there are nodes available to run them. Depending on whether it's running the smoke or full tests, and depending on whether it gets a fast or slow compute instance, the tests take about 15-40 minutes, which makes them either slightly slower than the nova unit tests, or much slower. > Part of the problem is that the CI system runs Tempest on the same CI > node as the OpenStack environment that devstack installs.

But how much more RAM would parallel tests require? If we need to increase the node size (we're at 4G now), we can, but I don't want to do so unnecessarily. -Jim -- Mailing list: https://launchpad.net/~openstack-qa-team Post to : openstack-qa-team@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack-qa-team More help : https://help.launchpad.net/ListHelp
