[OpenAFS] cache performance

[Todd M. Lewis]

Okay, it's starting to sink in now.  I tend to think of us as a largish 
AFS shop because we have lots of users, but we aren't physically 
distributed (all our servers are in one room I believe) and we're more 
concerned with monitoring individual application use rather than volume 
use (though they are closely related in most cases).

I look forward to seeing what you come up with.  Sounds like anything 
that makes managing AFS easier on your scale is probably going to scale 
down in a way that's useful to the rest of us.  Good luck.
