Slow upload speeds

[Commons_Helper]

I have a 50/50 connection that has an easy job getting to 50Mb down in short order, but my upload likes to stay mostly idle.

There have been a few times when I was the only seed and I was able to sustain 50Mb up for 6 hours during the 5pm-11pm rush, but most of the time, even when there are 1:10 ratio of seeds to leeches, I typically stay under 256Kb/s upload.

I know my connection can handle it, and it obviously works when I am the only seed, but most of the time, I'm not uploading anything.

Even with 47-50Mb on both up and down at the same time, I still can maintain 10ms pings to Chicago, just a bit of periodic jitter, sometimes into the 20-30ms range when completely pegged.

I have uTorrent set to 512 global connections and 128 per torrent with 16 upload slots.

I have a Netgear 3700, which has been benchmarked to 450Mb/s WAN to LAN with a 2,000 connection logical limit, on 3rd party sites.

And your utorrent version/build is?...

Did you check if your port is open/forwarded correctly and not being blocked (firewall/router) ?

uTorrent 3.3 b29625

I see the port open in my router's uPNP table

UPnP Portmap Table

Active Protocol Int. Port Ext. Port IP Address

YES TCP 19935 19935 10.0.0.2

YES UDP 19935 19935 10.0.0.2

I was one of a few seeds again for a few torrents last night and I was uploading a lot again.

Again, downloading is really really fast, but my upload tends to only work when leeches super-vastly outnumber seeds.

It is entirely possible that no one wants anything from me, but some of my torrents were along the lines of 200 seeds and 900 leeches, and I had 0MB uploaded . At least it downloaded quickly. The funny thing is while many of these torrents are not uploading anything, some of my torrents are uploading a lot, but those are the ones with almost no seeders.

Mind you, the kind of torrents I have been doing are creative commons and GPL like Linux. There may be a bias of strong seeders, but many years ago as a kid, I remembered always seeding when downloading anime.

Hmm... mine doesn't have a upnp table... Just make sure and test it here: http://www.speedguide.net/networktools.php

There is always the occasional firewall in play too ...

See if disabling the upload limits helps. I can recommend updating to 3.3.1, since there were issues with this limiter that they've fixed in there.

A private tracker then with grossly overseeded jobs because EVERYBODY is trying to keep a impossible ratio.
