Hi Doug,

In Classic mode, all networking has to be rewired to
go through OS X networking protocols, so that's one
explanation for the delay.
Another is that MacOS pre-X never had a really robust
TCP/IP stack, and was alywas a bit on the slow side.
But maybe someone else can offer you hints on speeding
things up.
