> Hello.
> I see huge performance degradation in 2.1 in admin UI regarding user search.
> When I go to the usertab or trying to add users to policies, interface just
> hangs for some time (up to couple minutes).
> !image-2020-10-19-10-51-12-692.png|width=203,height=147!
> and at the same time one of the CPU cores consumes up to 100%:
> !image-2020-10-19-10-33-03-264.png!
> Before I've build Ranger based on 454537a95494477312b592256cd38878d004a167
> commit, and it worked just fine on more than 10k synced LDAP users.
> Now I'm experiencing problems even on much smaller number of entities, using
> the same hardware configuration.
> Please advice how to proceed. I would like to try features of new versions.
> Thank you.
