1) test whether using cake as link layer adaptation mechanism works: put in a number for overhead and run “tc -d qdisc” and post the output of:
	a) cat /etc/config/sqm
	b) /etc/init.d/sqm stop ; tc -d qdisc
	c) /etc/init.d/sqm start ; tc -d qdisc

2) test whether you like the performance under load, http://www.dslreports.com/speedtest is a good start, registered (for free) users can change the configuration, I like to use 16 streams for upstream and downstream each and I like the “Hi-Res BufferBloat:	 (10hz check)” option.

3) test even more, have a loo at flent (https://flent.org), especially the rrul test has been a real help in understanding link behavior under load.
Please note, piece_of_cake will only use 1 priority for all packets (so effectively no priority), layer_cake.qos will by default, use 4 different priority layers, so expect some difference between layer_cake and piece_of_cake in the rrul results...

Best Regards
