Hi again, I got a simple theory about escaping torrent shaping without tunneling. From my observation, what you need to do is
a) forward port below 1024 range, use port 25,80,88,110 just to be safe
b) decrease p2p connection timeout below 30 seconds, I'll set mine at 20 secs
c) do not use forced mode for BT encryption it will get you less peers, just leave it default. AFAIK the tc device is not capable of layer 7 deep packet inspection. Besides it doesn't make any difference protocol encryption or not, it control based on initiated connections count. When your connection hits the count limit, you'll get lame speed.

I'll try these settings for a few days & see how it goes.

not that, but for that setting IMO is better set at a larger number e.g. 500 or 1000

Maybe BC doesn't have this setting after all 
if your connection is unthrottled then leave it at 100ms

SArawak and sabah the customer is less than northern region still kena throttle down to the root.
Up till now very hard to achieve 10kBps dl speed
