This benchmarks demonstrates a flaw in the Amiga Janus system
for the 2286 "AT" BridgeBoard. The 2286 is an order of magnitude
slower to "ACK" a packet sent to it from the Amiga.

To run the benchmark:

	Start up "amw.exe" on the PC side.

	Run "bench" on the Amiga side;  optional argument specifies
	number of loops in test, defaulting to 100.

	At end of test, PC side exits.

Hopefully, this benchmark will help track down the root of the problem
and help Commodore enact a fix. Any questions should be directed to:
