Jeremy, I don't have exact numbers, so yeah, it's just an assumption based on looking at the nova-api/scheduler logs with connection_debug set to 100.
But that's a good point you are making here: it will be interesting to see what difference enabling of PyMySQL will make for tempest/rally workloads, rather than just running synthetic tests. I'm going to give it a try on my devstack installation.
