Why not compile Bfgminer with http-proxy ?
I'm running 4 cube miner with Raspberry PI with Bfgminer as proxy using "--http-port". It only consume about 30% of the CPU for whole week.
hagenuk - do you use any switches to launch your BFGminer Stratum Proxy on your Pi?
I've seen references to --rt and --nm (midstate data) and --q and I cannot find the readme that details these
I'm using no Switches on my Pi BFGMiner Proxy (apart from --http-port XXXX) and after about 4 hours is reporting the expected 38Ghs now
So seems to be working ok, but if it can work more efficiently..... Then I feel compelled to make it so.
I am not sure how that all works.... yet
