Why should you not raise it above 12,288? What evidence do you have to
support that? This is an issue near to my heart, so I would appreciate
any details you can provide.
I do agree however that leaving maxusers at 512 and increasing
NMBCLUSTERS is the answer. IIRC, with maxusers at 512 there are around
8,000 mbuf clusters, so something higher than that would be the place to
start.
