We need more input on this topic I think.
Unless the LW on your server is also uploading to others which might be using up the server's bandwidth or the upload speed setting is limited, I'm not sure why you are getting such low speeds.
Downloading from multiple hosts always helps speed up the downloading process. Some might be giving you over 200 KB/s, or even over 500. On average 1 MB/s would be over 100 KB/s from each of the 8 hosts of course if 8 is the no. of hosts.
For speed test; Choose nearest location for a speed test & only have your browser open (without LW or any other internet program open):
