Hi Peter

thanks for your reply.

At Control_Panel/DebugInfo I see
---------------------------------------------------------------------------
None	 (44921)	
Tue Sep 30 13:24:18 2008 (0.37s)	(... 'ACTUAL_URL': 
'http://fog:8086/Control_Panel/DebugInfo/manage_main'}) (641)	
None	(57523)	
None	(69795)	
None	(47637)	
Tue Sep 30 13:24:17 2008 (1.18s)	(... path/to/any/doc')}) (48335)	
---------------------------------------------------------------------------

I sometimes see a LDAP call in the DeadlockProfiler output so it could 
be the reason.

Do you still have the LDAP patch around? I'd like to do a
timing of the connections, too.
