[horde] Horde/IMP with Turck MMCache

[Daniel Eckl]

Well, while this will work around the problem, this will have performance 
losses if a script is bigger than the free shared memory space configured in 
mmcache. In this case, the script will not be cached at all.

If you know your application and it's size and have enough RAM, you can give 
mmcache enough RAM to cache all scripts.

If not or just to be sure I suggest to keep shm_only=0 and make a change to 
the start stop scripts of apache so that it deletes the mmcache directory on 
every start and reload. This will make the problem disappear and if mmcache 
shm size is smaller than the to-be-cached script, it will be cached on disk 
quite fine.


Best,
Daniel
