--- Comment #11 from Marek Zarychta <[email protected]> ---
In the recent past, I experimented with running an RSS-enabled kernel to
benchmark network performance between the jail and the host. It did improve
forwarding performance over epair(4) — in my case, throughput increased by
roughly 3×. However, the primary bottleneck remains the single-threaded nature
of bridge(4), so if you are using epair(4) together with bridge(4), you should
not expect significant performance gains solely from running an RSS-enabled
kernel.
