Title:
MySQL tests significantly slower than PostgreSQL tests
Status in OpenStack Identity (keystone):
Expired
Bug description:
Running the keystone opportunistic mysql and postgresql tests locally
I noticed that the mysql tests run in 18-19seconds each and the
postgresql tests run in 4-5seconds each. This may be a performance
issue in keystone itself, in mysql, or in the test framework but it is
likely a good idea to sort it out.
My setup is an Ubuntu Xenial virtual machine running mysql 5.7 and
postgres 9.5. I am running the tests serially so that they do not
interfere with each other.
To reproduce make sure you have mysql and postgresql configured as in
the gate and run:
tox -epy27 -- --concurrency 1
Then compare the test run times.
