Don't think there are any "best" settings.  I personally would suggest  
more than 64 MB of shared memory size, or else a bunch of your scripts  
aren't going to get cached.

In this day and age, 64MB of program data for something as complex as  
Horde is not nearly enough.  If using even 2 or 3 Horde applications,  
you will likely fill that cache space quickly, which means you will be  
running a bunch of scripts unoptimized.
