I've upped it a bit, but it would require a server restart to get the
new setting into effect.  This is relatively "expensive" for us.  Does
anyone else share the viewpoint of Nasby, and does anyone have
recommendation for a good value?  Our previous value was 200M, and I
don't want to go to the extremes just yet.  We have 6G of memory
totally.
