I have a ubuntu 12.04 server that seems to use all available bandwidth on a server once I start a download. I have tried limiting through the limit options on available commands and I have also tried using wondershaper and trickle. Again even when I have put the limits in place the bandwidth usage maxes out. Does anyone know why this happens? I can verify that it happens when using wget, sftp and ftp.
As a side note, the download speed never goes higher that 1.00mb/s even if it uses all the bandwidth.
