Add me to the non-fans of download.com, I used it to get the v5 installer only because Alwil's own servers are obviously in very heavy use.
Took 14 minutes using FreeDownloadManager -- download.com permitted me to use my max. 10 sections, but top speed was only around 60 KB/s whereas I can get 300+ from most good servers. I think my ISP throttles me to around 25-30 KB/s per connection -- it would have taken me only twice as long to ignore FDM and use Firefox's built-in downloader (single conection).
And I don't know about these upgrades steckler mentioned ... seems like quite a few of us got poor download speeds. And it's nearly midnight (Eastern time) here, plus I'm not exactly out in the "boonies" (about 60 miles from Toronto), so I would have expected much better.
On top of which, at one time (they may have corrected this by now) download.com was notorious for badly out of date with regard to current versions of whatever.
