So, I'm running the tempest tests and they are pushing the load average to 80. The tempest tests are the integration tests used in OpenStack. They run scenarios which confirm the APIs of the various services and the abilities of those services to interact with one another. They are one of the keys in TheGate.

That the tests are intense is not a problem. What's a problem is that the tests are loaded with things that are expected to happen in sequence with reasonable time intervals. That's challenging when:

• the tests are run in parallel
• eventlet is being used

Things aren't going to happen to a nice happy clean schedule.
