Big performance loss after upgrade
«

Hi
This is the topology:
.-----+------.
| O igb0 +
| P | .------------. .------------.
| N igb1 +--Trunk--+ Switch +- -+ RPi |
| s | .------------. .------------.
| e igb2 +
| n | .------------.
| s igb3 +----------+ Laptop |
| e | .------------.
.------------.
RPi is connected to an access port in VLAN10
Laptop is connected to default LAN interface on OPNSense (no VLAN)
igb1 is connected to a trunk port, native VLAN10 and some other ones tagged.
(i know it might be better to change to everything tagged, I planned to do that in 22.1)
Before Upgrading I performed iperf3 tests and got throughputs ~900MBit
After Upgrading the same test shows ~300MBit
No changes were made to any config.
I have read through some articles of
https://github.com/ocochard
There I also found the bridge performace issue in FreeBSD12 which was one of the reasons to update OPNSense to 22.1.
Question:
How to debug where this bottleneck resides (I'm very sure it is inside the OPNSense box)?
What board tools of OPNSense / FreeBSD13 can you recommend to look at?
I suspect it has to do with Queues/number of CPUs bound to the interface/interrupts/whatever?
Cheers

Ok,
lacking the skills to really follow @ocochards benches I chose to do what he calls "drunk method".
I tried out random things.
In the end I reinstalled the box with OPNSense 22.1 and rebuilt the config today.
What can I say... performance is back.
Thanks to FreeBSD 13 I even can use bridges to transfer SMB ~50 to 75 MB/sec. now
I suspect some tunables carried over from 21.7 might have caused my issues, but this is only a wild guess.
Just wanted to let the internet know what solved the problem for me.
Cheers
