1 start, 8 data, and 1 stop bit = 10 bits per transferred byte.
A standard ping packet contains 64 bytes -- 640 bits in this case.

Transferring 640 bits at 9600 bits per second would take ~0.067 seconds.
IOW, even with no other factors involved, it would take 67ms to cram the
entire ping packet through that pipe.

I'm with Glynn here -- if you're concerned about speed, consider a couple
cheapo network cards and a crossover cable.
