Bob, Steve, Dave,

Is there any progress on tuning the size of the tables (RHEL5) to allow 
larger values and see if they help things as far as caching goes?

It would be advantageous to tweak the dentry limits too - the kernel 
limits this to 10% and attempts to increase are throttled back.

This doesn't scale for larger memory sizes on fileservers and  I think 
it's a hangover from 4Gb ram days.
