Half upload speed if traffic shaping enabled

cfosspeed must slow down the upload speed to ensure a small ping value.

try switching off rx shaping: click context menu, traffic shaping, open console and enter: "spd gset rx_shape 0 -save". that should help.

Hello.
I got upload speed 10mbit/s on vdsl connection, but if I enable traffic shaping, my upload speed drops to 4,8mbit/s.
Is this a known issue on cfosspeed and is there a solution for it, or do I uninstall the software?
