Hardware and Performance / Re: Very Slow IPSEC bandwith
« on: February 09, 2022, 03:46:28 pm »
Hi,
Our OpnSense (DEC-3850) is at the moment: 21.10
because of a maintenance from our datacenter provider, we where able to shutdown IPSec VPN and tested quickly again with iperf3 from one VLAN to another VLAN, so it goes over the OpnSense appliance. We had ~1Gb/s more throughput. So instead of ~3Gb/s we had nearly ~4Gb/s.
I'm not sure, if we can reach max ~5Gb/s in theory, because the traffic has to go twice over the same OpnSense Interface (which is a LACP 2x10Gb/s). But .. one important thing came into my mind: Before we switched to the DEC-3850, we had a real server (Supermicro x11SSH-LF) and reached ~5Gb/s. But anyway ...
The other mention you found from me (just found that thread after this one and I've found out, that traffic from one VLAN to an other one is also pretty slow ): It is the same setting, sorry if it was not clear. I've tested every combination, in the moment, OpnSense jumps in .. the throughput breaks down. The question for me is: is that expected, that the "speed" goes under 50%, from what is in theory possible.

But 20% from 2,5-3 is not 10 though the real question is how realistic that assumption is considering IPsec is running in the first place and may be a feature from the firewall is used. Or I'm reading this wrong...
Cheers,
