[CentOS] Network throughput testing software available for CentOS/Linux

Hello everyone,

A network engineer buddy of mine brought up for discussion with me that he'd like to do some throughput testing, but he's new to Linux/RedHat. Is there any software I can recommend to him that any of you find above par for CentOS 6/7?

Thanks!

Gilbert
