22.02.1- Limited to 10gb throughput?

[Tristram]

Hi All,

We're testing out Scale in our lab and have run into something that sure looks like a 10gbit speed cap. We are able to transfer in and out of the unit at 10gbit but when we run an Iperf3 on top of that transfer we find ourselves capped overall to 10gbit still. The server in question has 25gbit NIC's up in 25gbit:

I've had a hunt around but nothing is jumping out at me, is there a 10gbit cap somewhere either via license or by a sysctl?

I'll leave it to someone at IX to confirm, but I doubt that. I am running TrueNAS-12.0-U8.1 (Core) and I can get 39Gb+ with iperf over the 40G links between servers. Do you see any errors on the interface in question in the output of a netstat -in?

No errors and the system under different OS's has pushed 20gbit no sweat in the past. Will keep tuning and tweaking to see if i can break 10g
