--- Comment #7 from Michael Tuexen <tuexen at freebsd.org> ---
I could reproduce the problem using the settings of tjh at . More precisely,
r362879, in a bhyve VM using a GENERIC kernel with TCPHPTS added, I observe a
5% to 6% interrupt load. Using r362880 this does not happen anymore. Also I
don't observe an interrupt load on VBox with an up-to-date stable/12 machine.

I think the issue is already solved by
https://svnweb.freebsd.org/changeset/base/362880 and therefore I'm closing this
issue. If the problem can still be reproduced on a system with r362880 or
higher, please reopen.
