Try changing some settings in
1. The "SmartDefense": I found that it can lower the download speeds at upto 25%-30% and the upload to something close to 10%.
2. The "Traffic Shaper": either disable it (remove the 'V's from the connection or set it, about, 5% higher than the speed you connection has.
