Hi, i estabilished my upload and download speed, in uTP only, seting up net.utp_target_dealy +60000 I limited upload speed in 80% total capacity, and upload now fixed, and transmited no dowing... And torrents download in most speed but i changing traffic to potential peers had upload speed clear... This config "net.utp_target_dealy +60000" need stay default, and peoples need low ping, config manual, but all peoples dont understand if ping is better or not... This config set up 60000, all network download and upload in high speed, and peoples need slow ping, configure your clients..
