Maybe something like /usr/ports/benchmarks/iperf
But I don't recall options and arguments.

Fess: Well, you must admit there is something innately humorous about a 
man chasing an invention of his own halfway across the galaxy. Rod: Oh 
yeah, it's a million yuks, sure. But after all, isn't that the basic
