Title: Does zenarmor get any benefit from RSS?
Post by: Vilmalith on July 08, 2022, 11:46:40 AM
I am testing RSS on my topton i5 2.5gbe device and have noticed in game/app decreases in latency.  But there is a Zenarmor warning about possible issues when it notices that RSS is enabled.  Though it doesn't go in to detail about what these issues could be.

Is Zenarmor fully functional and performant when RSS is enabled?

Hi,

It is determined a performance issue on netmap when RSS is enabled. So it is added a warning if RSS is enabled. Your latency is most probably due to the netmap issue.

The warning label seems to need an update, it reads

RSS (Receive Side Scaling) Enabled
It looks like you've enabled RSS (Receive Side Scaling) kernel support. Please be noted that RSS support is quite new. If you experience throughput problems, please disable RSS and try again.
You can check if RSS is enabled in the System - Settings - Tunables - net.inet.rss.enabled=1. Please remove the entry to disable RSS.
