Dear Horde team,
I have noticed some performance issues in Horde with email "power users"..

"Power users" are users having > than 150 message folders and 25k  
messages in them.. (just to have an idea about what I'm speaking)

Every time a power user logs in via ActiveSync (Outlook 2013, ..) the  
apache service rises up to 100% CPU usage for 3-6 seconds.
Also, every time a power user mark just 1 message as read/unread the  
same problem arise.

The bottleneck seems to be just the Horde service (apache).
There is practically no access to harddisks and/or other hardware  
during the CPU usage spike.

Is there any possibility to investigate further?
Could there be some needless loops in Horde that could be optimized?

Thank you!
