Description

On a 8 core machine -

sudo suricata -S /dev/null  -vvv --pcap=eth0 --set pcap.0.threads=auto --runmode=autofp --set threading.detect-thread-ratio=1
...

sudo suricata -S /dev/null  -vvv --pcap=eth0 --set pcap.0.threads=auto --runmode=autofp --set threading.detect-thread-ratio=2

I would expect the first run to have 8 packet processing threads and the second 16 packet processing threads.

Seems to working as intended. There is 1 pcap receive thread, and then 8 and 16 'workers' as configured by the ratio. The ratio is applies as core/ht count * ratio. So this should be a box with 8 cores/hyperthreads.

Yes indeed - I forgot that 1 receive thread!
Wonder if it is worthed adding that to the output with autofp? (aka something like "all 1 pcap receive thread, 16 packet processing threads, 4 management threads initialized,")
