How do you measure 250Mbps?

Few things can use Gbps Ethernet to the full without tweaking. If you
are getting more than 100Mbps than the gigabit Ethernet is probably
working as designed.

I did some benchmarking using some new kits at work a while back, and I
could get good speeds over a single FTP connection but no where near
1Gbps. Using SMB protocol connections with lots of small files (i.e.
what we actually use the boxes for), the numbers were depressingly low
but they just reflects a chatty protocol with lots of round trips and
other overhead.
