Improving uTorrent Download Speeds

I'd make that a last resort, specially if he has a router. Opening many connections will do nothing in the best cases, and slow you down in the worst ones. :)

Ok I will try that

Something interesting happened today which I discovered by a fluke, but may point me in the right direction.

I normally have about 50-100 torrents active at any given time. ( Doesn't mean they are actively seeding )

I checked to see what would happen if I stopped all torrents except for the one downloading.

In time speeds increased, and eventually got to 1.0 MB/s though it wasn't steady

I then checked to see what would happen if I activated 25 torrents, and immediately the speeds dropped to below 300KB/s

I don't have any active torrents now, except for a test download, but that one is only at 300kb/s or so

I've also tested another torrent client Deluge and that one averages about 500KB/s

So that's my update, I'm not really sure what to make of it.

Sorry, let me rephrase that. What I meant was putting around 20-40 if your tracker's userbase is ~6000, and 60-80 if ~20000, etc. Sorry :)

I see you've changed the net.max_halfopen value to 50, but is your TCPIP.SYS file patched to allow that?

No worries! The values you mention are quite rational. :)

No it isn't :ermm:

As this is a new computer, I haven't done any of those things.

What should be the default value?

btw - thanks for the help

Then you could try either patching the file or setting net.max_halfopen to its default value of 8. :happy:

Ok cool, I will set it to 8 for now.

Also, is there something that could be modified here?

Personally, I've changed a few of those settings to reduce long-term disk wear-tear, but for the average user yours are just fine.

I think you should set Seed While Ratio is <= 150% to -1. Don't know if this option even is working (i always have -1) but who knows, some of your torrents may stop seeding

That probably makes torrents immediately jump to the "When uTorrent reaches the seeding goal" condition, which is either limiting your upload speed or stopping them entirely. Automated hit & runs aren't really a good idea. :dabs:
