[c-nsp] Buffer Tuning pointer?

[Scott Granados]

I'm using a 7206 NPE-G1 and noticing a lot of buffer misses.  Everything 
that I find via Google points me to opening a support case but provides very 
little background information.  There's also a "buffer tune automatic" 
command but little listed about it's proper use.  Does anyone have a good 
buffer tuning pointer or pointer for good fundamental / n00by information 
concerning buffers?

Thank you
Scott
