netlink sockets creation and deletion heavily modify nl_table_users and nl_table_lock. If nl_table is sharing one cache line with one of them, netlink performance is really bad on SMP. ffffffff81ff5f00 B nl_table ffffffff81ff5f0c b nl_table_users Putting nl_table in read_mostly section increased performance of my open/delete netlink sockets test by about 80 % This came up while diagnosing a getaddrinfo() problem.
