By the way, i created a test case that multi-user query sahara by api at
the same time. I found that the qps is about 10-20. I can see when a db
query occured the eventlet switch to another keystoneclient thread and
switch back about 1 seconds, so the query qps is quite low. I wonder is
that the performance bottleneck of eventlet + mysqldb ?
