This reminded me of something. I remember reading some website
(possibly Cisco's) earlier, and they mentioned 10 GBASE-T had
much higher latency than other 10 Gbit options.
Have you paid attention to this? How big is the difference nowadays?
Or I wonder if it was just on some specific product..
http://en.wikipedia.org/wiki/10_Gigabit_Ethernet says:
"10GBASE-T has higher latency and consumes more power than other 10
gigabit Ethernet physical layers. In 2008 10GBASE-T silicon is now
available from several manufacturers with claimed power dissipation
of 6W and a latency approaching 1 microsecond"
1 microsecond doesn't sound bad.. :)
