ESIX seems to default to a rather small amount of buffers. This
may be for those sites with little memory. If you have alot, up the
FFSBUFFERS in /etc/conf/cf.d/stune to something bigger. I think
this parameter refers to the number of 8K buffers reserved.

If you don't use FFS, set this very low since it eats your memory.

Up the value NBUF made a huge difference on this box with the
S51K systems. FFS didn't seem reliable on this RLL drive but the 
S51K stuff works great.
