I have two roundcube web interfaces running on the same webserver. One of them has a slow responding UI, I already compared the config files. One is connected to a different mail server, but a regular imap client is just fast with that server.

How should I go about debugging this?

Compare performance between mail preview (or any mail related page) and e.g. Contacts page or Settings page. If the later loads fast then it's IMAP connection that is slow.

Test with all plugins disabled.

There's a plenty of debug options in Roundcube, the logs may give some clues.
