Even tcp_diag will be slow when all slots are dumped. It's a fundamental problem of the data structure. /proc has slightly higher constant factor overhead, that's all. Also there are some tricks to make it a little faster (e.g. the old patches to not take the lock for empty buckets) but again it's only just patching constant factors, not the fundamental scaling issue. > I propose 2 millions of entries as the arbitrary high limit.
