https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=287872 --- Comment #2 from Eugene Grosbein <eugen@freebsd.org> --- Also, I observe bad performance of the command ifconfig while the host has 814 network interfaces in total, including vlans: # time ifconfig -l > /dev/null real 0m0,836s user 0m0,001s sys 0m0,001s # time ifconfig lo0 > /dev/null real 0m0,840s user 0m0,000s sys 0m0,008s ifconfig does many netlink calls: # kdump -Ep 15771 | fgrep -c AF_NETLINK 165 devd runs many extra scripts and I suspect O(N^2) or even O(N^3) complexity of devd starting sequence where N is total amount of vlans created before devd starts. -- You are receiving this mail because: You are the assignee for the bug.
