when  it starts it  uses ages  on  purging only me  on  server and almost  no entities and when it is  finished it says purged 0 entities

While performing a cleanup plugin does check every entity on the server to find out cleanup candidates. To avoid the lagspike it checks one entity per frame, it's done this way on purpose. What's the goal of making it "faster"?

Because your plugin is configured that way.
