Issue

I have the Crowd2 Plugin version 1.x installed and it is slowing down my instance.
Furthermore, in the logs of the Crowd2 server I can see lots of requests coming from Jenkins.

Environment

• CloudBees CI (CloudBees Core) on modern cloud platforms - Managed Master
• CloudBees CI (CloudBees Core) on traditional platforms - Client Master
• CloudBees Jenkins Enterprise - Managed Master
• CloudBees Jenkins Team
• CloudBees Jenkins Platform - Client Master
• Jenkins LTS

Resolution

You should make sure to update the Crowd2 Plugin to at least version 2.0.0. In this version, a cache mechanism was put in place to reduce the number of requests sent by Jenkins.
