Hm, I don't think fetchmail is really comparable to Horde. But  
basically you want to say that your IMAP server seems to be slow?

I wonder why that should only apply to nag and kronolith then. The  
mail part should be affected as well.

But if only nag and kronolith are slow then this would indicate that  
the caching does not work. Are your 1103 loaded on *each* page call?  
They shouldn't. The purpose of Kolab_Storage is to use caching there.  
It may be slow on the first connect but should be quick after that.

Cheers,

Gunnar
