Hi All,
When we performance tested our federated authentication middleware recently we found that the time to authenticate (internal time measurement) / get an unscoped token (JMeter network time measurement) increases by some 50% with a password of 28 characters when compared to a password of 9 characters, I've detailed our results below for reference.
100ms longer processing time seems quite a lot and we were hoping someone could explain this.
Many thanks,
Kristy
