Well, by definition shaping at low rates is mostly using the timer infra, and its already 64bit. You'll hardly spend time in HTB. Note that psched_time_t is already 64bit wide. Only psched_tdiff_t is 'unsigned long', and the change I made in this patch will not change performance even on 32bit hosts. _______________________________________________ Bloat mailing list [email protected] https://lists.bufferbloat.net/listinfo/bloat
