Ok, here's the situation. I have 100Mbps internet connection, so I have set "Maximum connection speed" in Settings->Connection to 10000 KB/s. If I download something, without limiter, it downloads it full speed (around that 10000 KB/s). BUT if I set the limiter to anything, eg 50%, my download speed slows to <1000 KB/s, when it should be 5000 KB/s.
I'm running Windows 7 Ultimate x64, and alt.binz 0.31.1.
