If diffserv3 is used (without any further prioritization by manipulating DSCP bits) downstream is more stable and higher in throughput than with besteffort. Also, in my case disabling BLUE (by commenting out cake_queue_{empty,full} and all p_drop parts in sch_cake.c and cobalt.c) does not make any difference.
