Dear Bin,

I just downloaded several tarballs from ACD. Looks the download speed is OK for me (average 200KB/s).
Ouch, that's awfully slow. Are you sure the bottleneck is on the ACD side? How fast is your link usually?
I have a 15Mbps bandwidth link to the internet. Is the ACD supposed to choose wherever the nearest download site to the downloader for better speed?
Yes.
Hm, other prople have reported (ok - for bigger files, say 4+ GiB) download rates of 11 MiB/s (MegaBYTES per second) on a 100 Mbps fibre link, which is close to the theoretical limit there. So you should get better rates, I think.
The reason that I felt it is OK for me, is that for the original ftp.denx.de I could only get average 30KB/s when loading a tarball. Thus I am thankful for the new ACD :)
I'm glad if it helps, even though I can't explain why you don't get the full bandwidth.
Best regards,
Wolfgang Denk
