[horde] Slowness problem for Horde IMP webmail "New Message"

Dear Sir,

I'm setting up the Horde IMP webmail 4.1.3 in Redhat Linux 64-bit AS  
4, with PHP 5.1.6 and eAccelerator 0.9.5, with database engine of  
MySQL 4.1.20.

Everything is fine, except for a very slowness problem. When I spend  
around 25 seconds to open an Email folder with around 5000 messages  
and 140MB in total size, then I click "New Message" button it take at  
least 12 seconds(still acceptable) to load the composition page. What  
really annoying is that when I click "Cancel Message" or "Save Draft"  
at this moment it would take at least 1.5 minutes or 2 minutes to  
return to my previous folder, so it take at around 3-4 times longer  
compared to openning the same mail folder in normal case.

Would it be some bugs in the "Cancel Message" or "Save Draft" button  
of "New Message" page that introduce this serious performance problem?
