Below we describe how we were able to get and verify a 4x better performance of Keysone inside Apache. To do that, we ran a Keystone token creation benchmark with Rally under different load (this benchmark scenario essentially just authenticates users with keystone to get tokens).
Below we describe how we were able to get and verify a 4x better performance of Keysone inside Apache. To do that, we ran a Keystone token creation benchmark with Rally under different load (this benchmark scenario essentially just authenticate users with keystone to get tokens).
Goal
----
- Get the data about performance of token creation under different load.
- Ensure that keystone with increased public_workers/admin_workers values
and under Apache works better than the default setup.
- Ensure that keystone with increased public_workers/admin_workers values and under Apache works better than the default setup.
Summary
-------
- As the concurrency increases, time to authenticate the user gets up.
- Keystone is CPU bound process and by default only one thread of keystone-all process get
started. We can increase the parallelism by :-
1. increasing public_workers/admin_workers values in keystone.conf file
2. running keystone inside Apache
- We configured Keystone with 4 public_workers and ran Keystone inside Apache. In both
cases we got upto 4x better performance as compared to default keystone configuration.
