Apples and oranges? iperf tests a TCP connection (over v4 or v6) and
2544 runs Ethernet tests. Yes, both test throughput, but in very
different ways. Arguably you only need one or the other -- but you work
with what you have.

As you say, server hardware is heavy to lug around -- but you can fit
quite a lot of CPU in a Mini-ITX/uATX board these days, and newer boards
even come with PCI-E 3.0 capable chipsets (Intel Z87).
Given the right NIC (Intel, if I was buying one) and a recent Linux
distro... I'd be surprised if a recent quad core CPU couldn't generate
10G based on what I've seen our servers do.
