Was your cache using SQL?  There's simply no way that could be true.   
Horde_Cache using the same SQL driver backend with the overhead of  
Horde_Cache wrappers (and additional overhead in the IMAP Horde_Cache  
driver to correctly track the cache entries).

If your cache backend is local files... then obviously this will be slower.

I really could sit here and talk about these kind of performance  
issues all day.  But you've sort of touched on the endsum of open  
source software.  The software itself is free.  How to use the  
software - including such things such as "Which cache backend should I  
use?" - is where you get beyond the scope of open source software and  
into the scope of the consulting side of things.  Indeed - this is  
where I make a good chunk of my living: explaining to people HOW to  
setup their software for the best effect.
