Best speed settings

[ner ner]

I have been reading on here of several people that are getting very good speeds, several hundred kB/s at any given time. I was wondering if any of you speed masters would post your settings and what you think is contributing the most to these extreme speeds. I was happy with my speeds of around 200 max until I updated to 1.6. My max speed now only reaches about 75kB/s (between 4 torents! yuk!) and I am not very happy about it. I even went back to 1.5 but it didn't help. Something has gone seriously wrong.

Anyway, back to the settings......

Speed Guide generally provides the best settings. How does this torrent run?

Wow, ok, maybe my utorrent isn't messed up. That torrent reached nearly 400kB/s!!! the other 4 i am running didn't change. the numbers for this torrent that you directed me to, under "seeds" said 15(418), and under peers is said 1(65). what exactly do these 4 numbers mean?

I am guessing that the 418 has a lot to do with the lightning fast speed?

15 is the number of seeds (full copies) you see and are connected to. 418 is the number of seeds in the swarm, that is, how many people that have completed copies of the file altogether.

1 is the number of people that you are connected to but they don't have a complete copy. 65 is the number of people in the swarm that don't have complete copies.

I hope I explained that correctly and made some sense.

The maximum speed I have seen on µTorrent has been 1.8 Megabytes per second. On most torrents, I average around 1.3 or 1.4 Megabytes per second. I simply used the speed guide and set it for a 2 Megabit upload speed.

Connections per torrent = 100

Max Active Torrents = 9

Upload Slots = 8

Connections (global) = 750

Max Active Downloads = 8

I'm using Windows One Care Live!, and a Linksys WRT54g Version 4 router with the latest DD-WRT firmware, direct wired connection.

I currently have them set at:

Connections per torrent = 150

Max Active Torrents = 250 (I seed a lot)

Upload Slots = 8

Connections (global) = 400 (should be at 1000)

Max Active Downloads = 50 (unnecessarily high)

Invy what's your upload SPEED?

With those settings, you need to have an absolutely huge upload speed (2,400+ KB/sec) to make things run smoothly. Even if only 10 torrents are active and you have an average of 5 peers connected on each, that's still potentially 50 upload slots spread across all 10 of those torrents. With an upload speed total of 100 KB/sec that'd only be 2 KB/sec per person on those torrents.

Upload slots need to be reduced when you have lots of torrents at once, especially while seeding -- since none of the peers have anything they can give you back anyway!

[Invy]

I only have around 50kB/sec upload. An average of about 10 torrents have at least 1 peer at any given time, and I currently have about 250 torrents in uTorrent, all in seeding status.

I guess it is overkill... but memory-wise and cpu usage-wise, it doesn't seem to effect me surfing the web, burning dvd's, watching movies, etc.

For my 512/256 DSL

Connections per torrent = 50

Max Active Torrents = 10

Upload Slots = 3

Connections (global) = 275

Max Active Downloads = 10

in Advance setting

net.max_half open = 48

bt.connect_speed = 96

speed 50~55 KB/s (with 5 torrent DL ,seeding 13 torrent my bad)

Invy, it's not your cpu or memory I'm worried about -- µTorrent is very easy on them. (...Azureus on the other hand. )

But you definitely have set upload slots too high. Splitting your upload speed thinner than 2 KB/sec per person means you're taking a long time to upload a single torrent chunk (which is often 512 KB, 1 MB, 2 MB, or even 4 MB) -- and until a peer gets a complete chunk it has nothing to share. Better to quickly get chunks out to single peers so they can share them...if it's a private torrent tracker.

kraijeck, your global connection limit is a bit high for your connection. The number of active torrents, net.max_half open, and bt.connect_speed is WAY too high. Even were your connection 10x faster, I'd still say they're too high.

When everyone talks about "Best speed settings" they seem to mean for them, or download speeds. But the ultimate limiting speed factor is upload speeds of others, which they typically will only send your way if you're uploading quickly to them. Uploading too close to the limits of the connection also causes major download speed drops -- so some people just set upload speed to 6 KB/sec and leave it.

Alright im downloading a 787 mb download, with 10(960) seeds, 71(6,532). My download speed is about 56.4-60.2, up speed 46.4-50.2. My light is also green as well, here are my settings:

For the Speed Guide:

upload limit-186 kbs

Upload slots-8

connections per torrent-100

max active torrent-9

connections(global)-750

Max active downloads-8

number of slots per torrent-8

Paulyboy, if you're only able to upload at ~50 KB/sec, then it does no good to tell µTorrent to try to go faster...by doing so it kills your download speeds (from what they would be otherwise) and even reduces average upload rate. Try firstly putting in a max upload speed of 50 KB/sec. Then check µTorrent's speed graphs to see if your connection is able to sustain evenly 50 KB/sec upload.

Also, if you're really running 5+ torrents at once, then you have upload slots set too high. Try reducing them to only 4 or 5. If your average upload speed per upload slot (which is all the upload slots across ALL your active torrents) is less than 1 KB/sec...or even 2 KB/sec in some cases...most peers won't upload much if anything back to you despite you uploading to them. Even the ones that DO upload to you will only do so sporadically.

You may also get better results with fewer total connections at once. More is not always better -- each one costs bandwidth just to maintain the connection. Try 200 total connections max and only 80 connections per torrent and only 5 torrents total at a time.
