--- Comment #5 from Tom Jones <thj at FreeBSD.org> ---
I think I can reproduce this on 12-stable (r362275)

With options TCPHPTS, I see a consistent interrupt load on a bhyve vm on a 12.1
host.

CPU:  0.0% user,  0.0% nice,  0.0% system,  8.0% interrupt, 91.9% idle

Without TCPHPTS the vm is almost completely idle and there is no interrupt
load.
