Maybe this was already covered earlier in this thread - Do you see the 
same poor performance with large mailboxes if they use a stand-alone IMAP 
client, such as Thunderbird?  You should record iostat numbers for that 
case as well.

That might help us narrow down if the problem is caused by Horde or if it 
is a problem with any IMAP client.
