	You should expect to be able to run all three GE interfaces at
about 50% with no problems.  I was moving slightly more than
800m on two of the GE interfaces during the beta with no problem.
That was roughly full-duplex 800m.

	It did cause the CPU to be fairly high as it's a central cpu
platform, but that should be expected.
