Thanks for the help, everyone!
since you have extreme slow connection, i would suggest to limit the number of peers at the settings - network - connections page. And you should disable DHT and Channels too, since these features generate some minor traffic, but in your case it can be relevant.
Any suggestion on what I should set the number of peers to? Also, are you talking about the "peer connect" number or the "maximum peer connections per transfer" number?
I've disabled the channels feature, so I'll see if there's an difference. What is this feature, though?
What do I have to do to disable DHT? Do I just put "Startup DHT mode" to off or do I also have to change "DHT mode for normal transfers" and "DHT mode for trackerless transfers" to search only?
Also, what IS DHT, what am I doing by shutting this off?
Both Tixati and uTorrent use KB/s for bandwidth limits. KB/s and Kbps are not the same units. An upload limit of 40 KB/s = 320 Kbps, it's more than your link can transport. This will most likely slow down your browsing. 70 Kbps = 8.75 KB/s, your upload limit should be about 70-80% of that, try lower limits, 5-7 KB/s for example.
Sorry, my mistake, when I said what my capacity was I was going by the speed I was getting at that moment when I wrote that (because I was seeding a torrent at the time) and the speed (in Tixati) was 70. So I made a mistake, the speed was 70 KB/s (I didn't realize KB=/=Kb).
So at the time I set the speed from 70 KB/s to 40/KB/s and it didn't make a difference.
I think with this speed you shouldn't seed more than one torrent at the same time.
With this new information about the upload speed, do you still think I shouldn't seed more than one?
I tested my connection speed with one of those online tests again, just to check, and it came out:
down: 4.90 Mbps
up: 0.46 MBps
Also lower settings of "maximum peer connections per transfer" may help (Settings > Connections), 25 is a minimum value.
I'll do this and see what happens.
One question, tho, on this. Could this impact my seeding? Like, suppose there's 50 people in the swarm, of which 49 seeders and 1 leecher. Might I be unable to connect to the leecher because my connection limit is 25 and I'm connected to all seeders and no more slots for the one leecher?
I'm guessing the answer is no, but thought I'd check.
Also be aware that ISPs may impose different limits at different times of day to maximise the overall bandwidth for local customers. For a while I suffered from a much lower upload limit during the evenings which only returned to peak close to midnight. It's possible you are trying to browse when your ISP bandwidth has dipped below the set limit.
The problem I'm having happens all the time, so this can't be hte issue.
