Dave. My actual speed with this setting , almost expected . Around 90kbytes per second actual speed = 810kbit per second actual setting speed * 48/53 considering atm connection. This settled speed doesn't include ethernet framing. Maybe , Bandwidth = without ethernet overhead tc-stab overhead = -14 is correct. Thank you .
