10GbE is really cheap these days(cheaper than 1GbE in some cases on a per Gb basis) if you need faster performance, and simple to configure, I wrote a blog on this a couple of months ago:

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.. :)

That PDF claims this:
10GBase-T: - latency 2.6 us - power per port: 4-6W/port - price per port: $400 - max distance: 100m
10 Gbit SFP+: - latency 0.3 us - power per port: 1.5W - price per port: $40 - max distance: 8.5m
