[OpenAFS] OpenAFS for Windows cache options

[John Perkins]

Some questions that have come up at our site recently after some review
of our OpenAFS client setup.  We're running Windows XP with OpenAFS 
1.5.52 or 1.5.30-36 clients.

1.  Is there a general recommendation for cache size these days?  We had
been setting the cache size to 1GB if there was what we thought to be 
enough memory on the host.  Recently that has caused problems on some 
computers, so we've reduced that to 512MB.  Still, this is much larger 
than the 98MB default.

2.  Is there a recommendation toward using or not using the 
"NonPersistentCaching" (virtual-memory cache or "normal" file cache)?

3.  Whether or not the NonPersistentCaching option is in use, 
the following command:
	cmdebug -server <hostname> -cache
returns the following as part of its output:
	Cache type:    memory
afsd_init.log shows cache type FILE or VIRTUAL as expected; it's just 
cmdebug that appears to be confused about this.
