Is it possible to have each interface use differently pinned worker threads?

In the af-packet block, I can configure the number of threads per interface, and then there is a global “threading” block, which can be used to pin threads to cores.

But what if, for example, I wanted eth0 to use 12 worker threads pinned to cores 0-11, and then eth1 to use 12 work threads pinned to cores 12-23.

Is that possible with the current configuration set?

Thanks,  
Jeff

For the same interface you should follow

> **[9.5. High Performance Configuration — Suricata 6.0.0 documentation](https://suricata.readthedocs.io/en/suricata-6.0.0/performance/high-performance-config.html?highlight=performance)**

For different interfaces you can use the suggestion here
