We have 2 core problems testing the 10Gbit interfaces: 1) A lack of external options on the internet for testing. We've found=20 it non-trivial to adequately saturate a 10Gbit internet connection in=20 2014, (without having one or two more 10Gbit connections to saturate).=20= =20 We simply don't have enough outside resources we control to saturate=20 our lines for reasonable tests. 2) We've done our homework on testing, but would love any input from=20 this audience about ways to measure any of these: - PPS (easier) - Maximum Socket Connections (easier) - New Socket Connections per Second (harder!) - Redline Throughput (easier) - Ways to measure PF performance, (state handling, etc...) - Ways to start measure/test ALTQ based shaping, as we experiment with it. Thanks for any input! Best, .ike
