Can anyone tell me the theoretical maximum download speed you might experience on an 8Mbps broadband service? If you can post up the calculations that lead to the figure it would be grand too. Thanks.
 
I always thought you divided by 8 and took off the TCP overhead transmissions - around 10%. So for 8Mbps:

8192/8 = 1024 (theoretical max)

1024 - (1024 * 0.1) ~ 921 KB/s (closer to real word theoretical max)

Although some people simply divide by 10 to factor in these overheads:

8192/10 = 819.2 KB/s

meh clubbing time!

lol :p

I can elaborate on my post if you want.

8Mbps = 8 Megabits per second. There are 8 bits in 1 byte.

So, to convert Mbps into MB/s (megabytes per second) divide by 8, which equals 1 MB/s.

A megabyte is 1024 kilobytes, so an 8Mbps broadband connection has a theoretical download rate of 1024kb/s.

Tada.

Legend. Thanks.
 
Yeah, I'd say around 800kb is the best you can expect. I get 650 best during off peak times from rapidshare.
 
I get about 800-850kb most of the time....the trick is to use something like getright to split up the file into 10 pieces and download from 10 different servers at the same time :D
 
Well, i used to get a steady 840 - 850 with my old isp (Zen) but since migrating to new isp last month (adsl24) i dont get above 800. Which still isnt bad but even then only happens on the odd occasion. Someone else on their service just said they download above 900 regularly which is what made me ask the original question.

I usually go by this theory. I get a max of 2.5Mb/s, so real world is around 250Kb/s which is almost exactly the average i get.
 
The most I have seen my download at was 839KB/s (on a torrent from OiNK - I miss that site.) This is on a 7.2Mb profile and 8128sync. The maximum I get on HTTP is ~820KB/s.
