Logins pause for a long time at 20%

Running:
OX 6.16.1 (OpenSuSE 11.1 repo)
Exim 4.69 ----------------------------------- SMTP

Problem: User logins (mostly 1st login of the day) pause at 20% for a LONG time. Often between 30 and 60 seconds.

Is there anything obvious in any of this which would cause such a nasty pause at 20% during login?

Hi,

at 20%, the login is triggered which includes access to the database or other authentication backends. You could install FireBug and check if the login request really take that long (Firebug console view). Otherwise the login can be slowed down by downloading the user interface data (html, js, css...). You might also check the ox groupware log file.
