Maximize Upload

<< < (4/7) > >>

@jaybug: Are you using windows XP?

If you are, there is a limitation on number of half-open connections that an application can have on this operation system after SP2. By default uTorrent is configured to abide this limit (in the advanced settings-> net.max_halfopen = 8) and it shouldn't be a problem.

The news is, I am seeing several warnings in my Event Viewer->System logs (in Computer Management) saying that I have exceeded this limit imposed by the operating system and can not upload beyond %30 of my capacity. When this limit is exceeded, the operating system automatically prevents the application (in this case uTorrent) from creating new connections to the peers for a period of time (hours?) and as a result you can not utilize your bandwidth.

If you are using XP and there are TCPIP warnings as a source in your Event Viewer->System logs having the message "TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts.", this might be your problem.

I don't recommend just plugging in the values and leaving them at that, but it gives a useful place to start.

I was able to sustain many more connections than previously when I did some tweaking to my router, but that's just one example of things that change from system to system.  Use your own judgement.

jaybug:
I'm using Windows 7. I haven't seen anything untoward about any half-open stuff. Yet....

I have played around with the bandwidth allocator by right-clicking the torrent and going from there. But I can't remember if any of the ones I am currently uploading are one of them. I'm at work, and I just wanted to let you know I've seen your posts.

BY the by, I thank everyone for their input.

I've been thinking about buying a different router, and getting rid of the cheap hunk of junk the ISP provided. Thing goes out and needs re-setting. You know when as everything acts as if it's on dial-up. Happens about every other month or so. Of course they say I may have problems, and describe what another router may do, which coincide with the symptoms I have using their router. And the drawback is what, I ask.

I'm thinking about maybe limiting my uploading torrents from somewhere from two to six. Just so that one of them will be at a much higher rate than the 20-30 I have been seeing lately. Maybe all the way up to 80! :o lol So does anyone know how to make utorrent only actually upload what I hit apply for, or do I have to finish uploading to all pre-existing leechers before what I have newly set will become applicable?

Just got home. And after I un-froze my computer, I noticed one of the torrent wasn't allowing DHT, and I wondered if that was something as part of these configuratoin changes I have been making since starting this thread. So I looked under and they weren't checked in the boxes. SO I looked at other torrents, and they allowed DHT.

But, going back to the Bit Torrent page in preferences, I noticed two un-checked boxes, "Limit local peer bandwidth, and Enable bandwidth management."  I see those and wonder what those do, if anything good, or make a real mess of things. TO me it's like seeing the DOOR AJAR light on a car. If I didn't have my door open, I may think this opens the door automatically, or something like that. Sometimes I think I have had far too many English classes in my life. My guess is that the first one keeps a peer from getting too much, the second seems to me to be redundant, I have already limited my upload to 300. Any ideas, or go with leave well enough alone?

All of our .torrents are marked private, which means that DHT is disabled on them.  This is so the tracker can get (fairly) accurate information about your upload and download statistics.
