Presently Im developing a new solution that will increase efficiency by 30% for some configurations comparing to what exists now due to special optimized algorithm.
During mining software uses capabilities of CPU and GPU as well as CUDA and OpenCL when possible.
For instance, my old Core2Duo notebook gave me 6Mhash/s.
Presently my product is in beta-testing and then Im going to sell it by subscription as it helps to seriously increase profit without expanding the farm.
30%... as compared to what? how exactly do you define efficiency?
Your CPU mining numbers sound like what ufasoft and cpuminer can already achieve.
