Today I was using this to download 4Gb ISO files from MSDN. Browsers failed, even the Firefox DownItAll! Plugin. It was slow, bursts of 100K with 10 second intervals. The speed was that of a bad modem. And it would hang up every 10 minutes and require a manual resume command.
After 10 hours and much hair pulling, found a post recommending disabling the SSL connection (Options…, Connections Tab, Uncheck HTTPS).
Wow. Download complete in 10 minutes. All in one piece. AArrggghhh.
