The build-in WP object cache (which you enable by     define 
('ENABLE_CACHE', true);    in wp-config.php) uses the filesystem to  
store the data.  Sometimes you get a speed benefit as compared to  
having to do the SQL queries on every load, but sometimes you don't  
(which is one of many reasons why it isn't enabled by default).

But it is almost always going to be faster to use a memory-based  
object storage engine than the built-in file-based method, as  
retrieving data from memory is orders of magnitude faster than  
retrieving data from a hard disk.

You can probably build an XCache object cache in an afternoon, so  
it's worth a shot.   Make sure you measure before/after speeds to see  
what kind of difference it makes!
