I have LDAP Directory as a user source and authentication vault. Working with Web Console I found that every time I'm clicking on "Users/Groups" tab, a lot of time needed to render that page. LDAP Directory trace showing every time that all users are getting by Openfire.
Why Openfire doesn't store initial request result in something like a Cache? If you have a lot users (in my case it's about 2K+), that's very inconvenient to wait when such a request will be finished. Anyway such requests provide high workload for both LDAP and Openfire server.
