It is very useful for network measurements, that involves running multiple concurrent instances of testing tools (primarily netperf and ping) For others to get easily started using this tool, I've written a mini-tutorial: http://netoptimizer.blogspot.dk/2014/09/mini-tutorial-for-netperf-wrapper-setup.html I'm currently using it for testing the Head-of-Line blocking issues that bulking packets from the qdisc layer can possibly cause. For that I've added an extra test called "tcp_upload_prio": https://github.com/tohojo/netperf-wrapper/commit/1e6b755e8051b6 More detail on these test results will follow (likely next week) -- Best regards, Jesper Dangaard Brouer MSc.CS, Sr. Network Kernel Developer at Red Hat Author of http://www.iptv-analyzer.org LinkedIn: http://www.linkedin.com/in/brouer
