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!
Take a look at some of the scripts in my netperf project:
g...@github.com:gvnn3/netperf.git
That uses Conductor:
https://github.com/gvnn3/conductor
which is still under development,
but the packet generation is just pkt-gen on FreeBSD with netmap capable
10G cards (Chelsio or Intel).
Bet,
George
