Oh and I wonder.... which one is better: multi threads or multi processes?
If i use multi processes, my worker's difficulty cant raise more than 2, lol but the hashrate remain the same as using multi threads.
Anyway, multi processes take more bandwitch, is that right, guys?
The hashrate using multiple processes is just a tiny teensie bit faster than using single process/multiple threads, but you have to benchmark/measure accurately to see it. You are right that using multiple processes will use more TCP connections and thus more internet bandwidth, but the bandwidth used by any one process is tiny anyway and the connection protocol used is very low on overheads, so it not really a problem.
The main benefit from using multiple processes is that it gives you the opportunity to connect to more than one pool and spread the hashpower across multiple pools.
And thanks NeedIfFindIt and cryptospout, i got XMG from your faucets already . And to tell the trust, im really hate AD banners, and i alway have ad blocks programs running, but today the faucets addresses are the first exceptions, as my thanks to the faucets owners About 0,1XMG/h is not a big amount with everyone, but with new miners like me, it's alot, lol. Thanks guys again.
