gigabit ethernet: does it always suck?

[Net Llama!]

I've been playing with gigabit ethernet a bit at work lately, and I've 
found it to be incredibly inreliable.  Sometimes I'll get 800-900Mb/s, 
and then other times i'm lucky if I hit 300Mb/s.  This is all on a test 
network with a fairly beefy Gb switch.

Even worse, is that sometimes I can't even get the NICs to autonegotiate 
to 1000Mb/s.

Someone please tell me that this is not normal?

I should note that if I fall back to 10/100 then all is good.
