Relation between download speed and file size?


Recommended Posts

I recently tried downloading a file that was around 6gb, and my download speed average was around about 40kB/s. However, when i downloaded another file that was around 50mb, my download speed was 250kB/s.

(This was after i completed the instructions in the guide given on portforward.com)

My ISP is Virgin Media (the worst ISP in the UK in terms of throttling), do bigger file sizes get throttled no matter what time of the day it is?

Any help or a simple agreement would be appreciated

Quite rotten ISP:



"50mb, my download speed was 250kB/s."

That was probably just a result of more seeds on the smaller file since it downloads quickly due to being much smaller.

You'll have to do more troubleshooting...1st and 2nd links in my signature, we need more information to go further.

Also temporarily disable: UPnP, NAT-PMP, LPD, DHT (both kinds!), and Resolve IPs (right-click in PEERS window on an active torrent).

Keep Peer Exchange enabled...though it only works with public torrents.

Lower bt.connect_speed to only 4 (outgoing new connection attempts per second.)

...And if that doesn't seem to help, lower net.max_halfopen to only 4 as well.

Reduce global and per-torrent max connections to 60 or lower.

Also possibly disable Teredo (IPv6) and uTP connections.

Disabling uTP is easiest to do on v1.8.3 betas.

Worst-case, try 'extreme' hiding tricks to get better speeds:


(Note: My post immediately following that one explains what settings in uTorrent are similar to the Azureus ones.)
