https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D241958 Michael Tuexen <tuexen@freebsd.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|In Progress |Closed Resolution|--- |FIXED --- Comment #7 from Michael Tuexen <tuexen@freebsd.org> --- I could reproduce the problem using the settings of tjh@. 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 machin= e. 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. --=20 You are receiving this mail because: You are on the CC list for the bug.=
