There seems to be a discrepancy between the download speeds reported by the app, and what you actually get....
While using newsleecher I average around 30-40 MBit/sec, while alt.binz reports a mere 7-8 MBit/sec, even though the download itself doesn't take very long (it may even be slightly faster than newsleecher)
Task manager seems to concur, as it reports much higher network usage while downloading, up to 80% of my 100MBit ethernet link
