Most likely threading only part of problem with iperf3.
As I say before - I'm check iperf3 in paralel by running multiple instanse on
diferent's ports
Speed is always same.
But maybe 2-3 instance to few for noticible result's.
For me most confusion was speed aroud 10Gbit on pure link showed by both iperf
and iperf3 ...
Any way. With enabled pf (set skip on gre0 in config) in kernel I get around
3gbit's and around 4.4gbit's without.
Also I'm tested diferent mtu on interface (eg 9000 and so on) no speed
improvement at all
Now question is - is it highgest speed of tunnel that we can expect from GRE or
there is some tuning capabilitis for speed up it?
In my Lab FW1 is only Xeon D with 95% CPU while testing and FW2 Xeon E
is at 20% CPU.
I cannot replace the Xeon D for the next 3 weeks so there could be more
perhaps.
