https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=287873 Bug ID: 287873 Summary: bad performance of devd(8) in stable/14 due to its hyperv.conf Product: Base System Version: 14.3-STABLE Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: eugen@freebsd.org CC: imp@FreeBSD.org, sephe@freebsd.org "service devd start" runs awfully slow (over 17 minutes in my case) for bare metal server having lots of vlans (800+) created with custom rc.d script before start of devd. Part of the problem is in /sbin/ifconfig's inefficiency if it uses netlink in 14.3-STABLE but another part is in the /etc/devd/hyperv.conf that has the following: notify 10 { match "system" "ETHERNET"; match "type" "IFATTACH"; action "/usr/libexec/hyperv/hyperv_vfattach $subsystem 0"; }; So, devd needlessly calls /usr/libexec/hyperv/hyperv_vfattach for every vlan created with bare metal server.
