torrent downloading

chump

Just a quick question...

I've noticed lately that my download rates with IOLBB are actually much better when I have a very low upload rate... ie. minimum with bitcomet 3kB/s ...

Now I knew you weren't meant to have an excessive upload rate but this seems a bit too low... I would have thought 8-13 kB/s would be reasonable to give...

Anyone else find this?

I'm actually typing this from a machine that uses eircom BB and I've noticed something similar ... ie. download rate drops when upload rate increases

commited

yeah - I found it too. I have limited upload, so I set it to 3kbps anyway, but for a while i had it higher (when i had bandwidth left) and dl's seemed alot slower!

Yep, on BT as well, and I've had my global upload speed choked to 13kbps (1/4 of my 128k upload bandwidth) for months.
...on individual torrents I find that leaving the upload speed at anything above 2.5-3kbps actually slows my d/l speed considerably especially in a torrent with a lot of peers. That's just the way torrents and ADSL work I 'spose...

BTW set your d/l speed to a 1/4 of your max speed so you have plenty of overhead for surfing or ftp d/ls...it's very rare that'll you'll hit a torrent that will even get close to that max d/l speed.

Just a little update... Using BitComet

Noticed a few issues:
TCP Connections: Established: 370 | Half-Open: 19 | Waiting: 65
LAN IP: 192.168.1.3 / WAN IP: 0.0.0.0

Overall Download Rate: 50 KB/s Connection Limits: 100 - 500 per task
Overall Upload Rate: 7 KB/s Upload slots: 3 - 20

The highlighted bits were set at around 40... connection limits 20-40
So I downloaded xp-AntiSpy, increased number open connections to 500 in winXP
I then went to bitcomet and changed the settings:
Max Connections per task: 500
Connections to keep per task: 500
Global Max upload slots: 20
Max half-open tcp connections: 500

I immediately went from 20-30kB/s up to 60/70, within seconds... might up the 500 limit now

Disable DHT or install Peer Guardian.

I get crappy speeds on Eircom BB..
The torrents show as everything is fine in Azureus but the download speeds are crap...

chump

you 100% sure NAT is OK
I have wireless eircom nat router, even tho I use IOL, and had a bit of trouble opening the ports...
