I honestly don't remember. It was mentioned by someone in this forum.

I do think, though, that for any given system there is such an optimal size.
It may be that on your workstation that size is measured in megabytes... on
others it may be a few K. I wonder how it feels on a NeXT that's paging over
the network or onto the OD?

Having "no trouble" with something doesn't mean you have the optimal
solution. Just that you have *a* solution.
