10Gbit Interface Testing

[Isaac (.ike) Levy]

Hi All,

In our relatively small environment, I'm looking for pointers in 
testing 10Gbit network performance, for internet-facing connectivity.  
Our enviornment employs pairs of routers running FreeBSD- also 
utilizing PF, CARP, and PFSYNC.

We have 2 core problems testing the 10Gbit interfaces:

1) A lack of external options on the internet for testing.  We've found 
it non-trivial to adequately saturate a 10Gbit internet connection in 
2014, (without having one or two more 10Gbit connections to saturate).  
We simply don't have enough outside resources we control to saturate 
our lines for reasonable tests.

2) We've done our homework on testing, but would love any input from 
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,
