after we found out serious out of memory issues on smaller embedded

with the result that cake takes a serious amount of memory. we use the
out of tree cake module and we use it class based since we have complex
methods of doing qos per interface, per mac addresse or even per
ip/network. so its not just simple cake on a single interface solution.
we made some benchmarks with different schedulers. does anybody have a
solution for making that better?

How are you measuring the memory usage, and what is your full config for
each setup? :)
me? nothing. i requested this test from a reporter and he uses just free
/ top. so there is a error tollerance.
but it shows a significant difference between cake and fq_codel etc.
cake is doing a OOM at the end
for the full report including config screenshots see this
https://svn.dd-wrt.com/ticket/6798#comment:14. it shows also the qos
setup which i can use to reproduce and to
print out the full tc ruleset if required (which it surelly is for you).
if you want i will recreate this setup and send the tc rules on this list
