The trouble here is that there's only 8 tins max in Cake. At that level selection is done with a linear search, which doesn't scale up, but is efficient for N=8. The host/flow mapping is hardcoded for speed with no override hook, because no consumer needs custom mapping of this sort. Fixing these problems to make them more ISP-friendly necessarily makes it less consumer-friendly. Hence the new project. Much code can be reused. - Jonathan Morton _______________________________________________ Cake mailing list [email protected] https://lists.bufferbloat.net/listinfo/cake
