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 ?
