Hi All,
Have a number of nodes using a mix of run(4) in a bridge with an em0(4) interfaces. All is functionally well.
However, I have found that releng/11.0 has a higher throughput than a snapshot of head (12-CURRENT) on an arm processor, in a controlled RF environment.
The difference is about 23% less throughput when using a snapshot of head (r308737) compared to releng/11.0 (r306211).
The only optimisation I have made is
Is this to be expected for a snapshot of head, or is something up? As a punt I am guessing that head has a load of additional debug overhead that could account for this?
The wisdom of the forum would be greatly received!

debug.witness.watch=0
set in /boot/loader.conf to twiddle WITNESS off. Is this to be expected for a snapshot of head, or is something up? As a punt I am guessing that head has a load of additional debug overhead that could account for this?
