I don't think this would help with find the best server for you to play. My best sever suggested by Realm is EUSW, even though I live in southern US. I have even tested multiple servers on Realm, EUSW lags the least for me. This program states EUSW gives me a ping of 141ms, but a majority of the servers show 50-52ms. However, I lag more on this program's suggested servers than a server that is in a different region.
