finally...speed problems solved

[mouser]

after struggling with these damn speed problems for the last 3 months i finally tried the last thing i could think of trying...which really should have been the first thing but yeah. i limited the amount of active torrents down to a handful (10 out of 900) and i was finally able to get a stable upload speed. i havent had an upload so damn consistent in 3 months and i really tried tweaking/changing/setting on fire every other setting in utorrent. the answer was right in front of me and so simple i decided i'd share it with you guys just in case you're feeling like you've exhausted all other options. i'm not sure exactly why but utorrent doesnt like thinking that it may possibly have to start seeding the 100+ torrents lots of us have loaded in our clients (even though 90% of them are never even actively seeding). i included the 5 minute view of my upload speed graph so you can see the "before/after" effect. the squiggly lines on the left hand side are when i had 100+ torrents seeding and the right side is when i narrowed it down to just 10 (3 of which are active).

everybody please listen to switeck and the other mods here instead of just pretending you've already followed the guides. if you're anything like me you followed 85% of what the guide told you to do but the parts left to be improvised on were the most important ones. i am so f'ing happy right now i could kiss one of you.

ps....forget my connection settings, just look at the statistics box on the left because that it shows exactly how little connections/peers it really takes to get good upload speeds. those damn guides were right...who'd have thought ?

Your upload speed is still set to unlimited...which is one of the first things we tell people to change.

Closest settings in my Speed Guide is probably the 2 mbit/sec upload settings.

If you're wanting to seed a lot of torrents at once:

1.Reduce connections per torrent to 30 or less. (While ONLY seeding, more than 10 is probably wasteful.)

2.Reduce upload slots per torrent from 8 to 4-6. (Set lower if you start lots more torrents.)

...Having done both of those, you could "get away with" seeding 20 active torrents at once.

What was your net.max_halfopen (default=8) and bt.connect_speed (default=20) set to?

They tend to cause disasters if set high...I even recommend lowering bt.connect_speed to 4-10 in uTorrent v1.9 and later due to Teredo/IPv6 and uTP connections both using UDP and not limited by net.max_halfopen.

net.max_halfopen=8 i've tried all sorts of numbers for this setting and nothing good ever came out of it. in fact, it dramatically reduced my browsing speeds when i set it too high

bt.connect_speed=12 i usually adjusted this one in conjunction with max half open

i've trial and error'd every possible combination of settings to the point that i just gave up on the idea of maintaining a steady upload rate ever again. The extremely crappy unreliable speeds i'd been getting (10-30kB/s) seemed to lean more towards the 30 side when upload was set to 0. i forgot to change it back to 186kB/s when i took the screenshot. i'm assuming the slightly higher than usual upload rate is because of the overhead. even when i was getting good speeds my upload was usually a bit lower (170kB/s). i was just afraid that if i touched anything it would all go to shit again

lol the moral of the story is that the more conservative settings were what made the real difference for me. i had to humble myself enough to simply follow the damn guide without making my own improvisations.

EDIT: the reason i included the statistics window was to emphasize that a handful of peers is really all it takes to max out my home line. the original speedguide recommendation of 750 is way too much. even with a ton of active torrents i never saw the # of connections go beyond 500. i could probably leave global max at 100 right now and still be ok

bt.connect_speed=12 means make up to 12 outgoing peer/seed connection attempts per second. Normally, that's also limited by net.max_halfopen on how many connection attempts can be going at once...but uTP and Teredo/IPv6 connections aren't subject to net.max_halfopen limit since they use UDP instead of TCP.

Even my "conservative" settings are anything but if you're only seeding. Upload slots become the limiting factor, so having far more peers connected on a torrent than upload slots does nothing but eat bandwidth and increase overheads:

Yes, if you can't max out your connection within the first 100 connections...generally the 650 extra connections past that won't help much either.
