Sorry, I never realized that I could only download 2 at a time.
That number is probably configurable by you, somewhere in your software.
The speed on this is about 200-300 kB/s.
Earlier you were concerned that something was wrong on your end, as your speed was 15 kb/sec.
So you have now discovered that all is ok, right?
When I download something from the internet on a good server it goes at about 500 kB/s.
huh?
That was the purpose of this experiment... to download from known good servers. ubuntu linux is usually available from a couple hundred servers at once, so download speeds might be up to almost whatever the limit is that is imposed by your isp.
