1. gigabit ethernet performance - Solaris 2.6, gem ethernet driver
Hi,
We have a Sun E4500, Solaris 2.6, with a gigabit nic installed.
prtdiag:

We have the switch port (Cisco 6500, i believe) set at 1000 fdx as
well.
The problem is this, inbound traffic gets only about a 6000 Kbytes/sec
rate, whereas the outbound goes at about 20000 Kbytes/sec.
Does anyone have any ideas why this would occur? I've searched
Sunsolve and came up with nothing.
Thanks in advance,
Jamie
