1MB, whats the maximum KB per sec?

Can anyone tell me the absolute maximum of download speed using a 1MB
connection? I am regularly getting around 100k per second, which I think is
a bit down on what it should be?? Is that correct, and what should I be
getting if it was performing at its best?

I think you're mixing your bits (b) and bytes (B).

You've almost certainly got a 1 Mb/s connection, and you say you can
download 100 KB per second. Remember that ADSL is also contended at
upto 50:1.

There are 8 bits to a byte, but by the time you add in overhead it's
generally a fair estimation to work on a 10:1 ratio. On this basis, a
1,000,000 bits/sec broadband connection that lets you download 100,000
bytes/sec is pretty reasonable.

If you are connected via an ethernet cable, and its speed rating is 10/100
you are getting the fastest speed you can get.For a 1mb connection you are
getting the full speed available.(going by your post)

I also have a 1meg connection, and just downloaded a podcast (18meg),
using the download manager in firefox, the speed started very high and
dropped to a stable 126kbs, pretty much as I usually get. So on that, I
would say you are a little down on what you could expect from a one meg
line.

I think he is referring to the WAN speed (external internet connection
speed) and not the LAN as you (appear) to be referring to.

100k a second download speed sounds a bit slow to me for a 1MB connection.
But I`ll leave the others on here to comment about that.

Working on the theory that my 512k connection regularly gives me around 61
kilobytes a second, then surely a 1MB (double) should give an average of say
122 kilobytes a second?

I`ll leave further comment to others. As I'm not expert on download speeds,
but the above assumption seems correct to me.

I'm sure someone else will give their opinion on my guess.....

Cheers

Barry

rough guide is to divide by 8, so 1Mbps divided by 8 gives 125 Kilobytes
per second.

100 Kilobytes per second means roughly 800Kbps which is within the BT
guidance for the product, and depends on stuff like contention and the
sending server as well as ISP transit.

My 1Mbit/sec nominal link reports itself as 1152Kbits/sec.
With 8 bits per Byte that should give 144KBytes/sec, but some of those
bytes are used for IP overheads

http://www.adslguide.org/tools/speedtest.asp
reports Downstream 965 Kbps (120.6 KB/sec) 1042 Kbps (inc.
overheads)

That is fairly accurate - downloads regularly run at 120-125K Bytes/sec
from fast sites. Watching download manager (which uses multiple
connections to optimise the link) it shows short term bursts of up to
130-135KBytes/second.

Ethernet is NOT the constraint. A 10Mbit Ethernet will run up to 10
times the speed of a 1Mb ADSL line, a 100Mbit Ethernet link is even
faster. A Wireless link could be a constraint - it has lots of
overheads.

Check http://www.broadbandreports.com/tweaks
to see if it thinks the settings on your machine need changing, and to
get some idea of any errors on the line.

Hugh,

Any chance you could send me the link to the download you have just done, so
I can compare my speed to yours with the same download site?

Thanks
