Another area which might need further investigation is better tuning of ncallout and callwheelsize. Right now, the callout wheel is sized on the assumption that there will only ever be `ncallout' callouts active simultaneously. (This is not a correctness constraint, but affects efficiency.) This means that the most efficient operation for machines with large numbers of outstanding TCP connections will likely require a partial decoupling of the two; since TCP allocates its own callout structures, high values of ncallout would needlessly waste memory. -GAWollman -- Garrett A.
