A MacTCP person sent me a message yesterday mentioning, among other
things, that they had gotten 3.3 mbit performance memory-to-memory.
Both numbers are rather respectable - 2mbit used to be a good
performance figure on a VAX. [The similarity between performance
figures is no doubt more than a coincidence. The same factors limit
performance in both cases.]
