OpenWRT changed the default fq_codel sch->limit from 10240 to 1024, without also adjusting q->flows_cnt. Eric Dumazet explains below that you must also adjust the buckets (q->flows_cnt) for this not to break. Eric explains: Limit of 1024 packets and 1024 flows is not wise I think. (If all buckets are in use, each bucket has a virtual queue of 1 packet, which is almost the same than having no queue at all) I suggest to have at least 8 packets per bucket, to let Codel have a chance to trigger. So you could either reduce number of buckets to 128 (if memory is tight), or increase limit to 8192. flows_cnt is now set to 1024/8=128 Signed-off-by: Kevin Darbyshire-Bryant <kevin@darbyshire-bryant.me.uk> |
