1024k BlueYonder Connection Not Using Full Capacity

If I have a 1mb connection with Blueyonder and start a download that
averages 128kbps why does it drop to around 60kbps when I start
another download from an entirely different server?

The second averages about the same 60kbps too. I would have thought
that both downloads would average about 128kbps since this is still
way below the 1024kbps maximum?

Whats going on?

TIA,

Colin

Because the other download is sharing your download ie 2 x 60kbps downloads.
It's all about bandwidth

You won't 256k download speed with 1MB!

512=60kb 1024=120kb or around so ya using all the bandwidth

Remember

Megabytes are not the same as megabits and kilobytes are not the same as
kilobits

So

Your 1mb connection actually equated to 128 kilobytes per second.

Sounds to me like you are running are maximum.

1024 is kilobits/second

128 is kilobytes/second

So max bytes/sec for 1024 kilobits/sec is 128

Two d/l at 60 kilobytes/sec is 120 kilobytes/sec which leaves 8kilobytes/sec
for overheads..

You will not often get 120kilobytes/sec download from one location as the
bandwidth at the other end will probably limit the bandwidth per single
connection.

1024 is kilobits/second download would be nice though ;-) Maybe in the year
2103!

you're confusing bits with bytes ;-) a 1024 kilobit/sec
connection will average around 120 kilobytes/sec, so you're
two 60 kilobytes/sec connections add up to the maximum the
link can support. If you were to open a 3rd download, they
would all average 40 kilobytes/sec, theoretically.

I regularly use a 100 Megabit/second connection at university. Plug my
laptop in and away I go! And yes, you DO get the full download speed if you
pick a time when the university is quite empty. Downloading ISO`s in a
minute is very nice :-)

It may open up new markets such as downloading DVD quality films on demand
(when in wide spread use of course). Even with broadband, a full film takes
an age to download.

Hmm..at uni I only ever got a max of 800k/sec. Booo.
