[tor-relays] Getting things right

I have a rooted Samsung S3 with CM 11 4.4.4 nightly build and would like to know exactly how to get the best for everyone involved on the network. My problem seems to be ram capacity and have tried every which way to improve that. Nothing seems to work as it has under 1 Gig of ram. How do I configure this for the best and not piss other users off. My binary skills are none too great but I'm willing to learn and am open to harsh comments to get me on my way. I'm quite a newbee at this and open to criticism.....
