Moving Torrents or Downloads stump Upload Speed
Postby northstar99 »
When I am not downloading anything, my upload speed works as it should. However, if I download anything, especially at fast speeds, the upload seems to throttle. I have a 1 Gbps down and 50 Mbps up, so it's not like the upload is anything monstrous for the download to bottleneck it out. It does seem like if I keep the download to less than 10 MB/s, it won't harm the upload. But any higher than that, especially in the upwards range of 60MB/s, the upload will constantly bounce up and down from full to 0 until the download finishes.
I believe when I move torrents from one drive to another (long process for big torrents) that there's no problem if I move just one. But just now I started moving about 8 x +GB torrents from one drive to another and the upload flat-lined to 0 and has say at 0 all day.
I have about torrents in Qbitorrent right now. About 25 TB worth of files being seeded. I believe I've tweaked the settings to be as upload friendly as possible, such as setting disk cache to -1 (auto managed), higher buffer watermarks, no limit to number of seeders etc What settings should I be focused on to help alleviate the upload issue when downloading or moving files?
If you're thinking it may be my hard drives which are bottle-necking, the current drive is an 8 drive RAID I think it had around a 1 GB/s sequential Read speed and something like MB/s seq write speed. Whatever it is, it's much faster than my internet connection and way faster than my max upload rate. The drive I am currently moving the files to is a 16 x RAID10 set-up which got a smoking 6 GB/s read & 7GB/s write (makes no sense, right?) for smaller writes of 50 MB a piece and GB/s read & GB/s seq write for 1 GB pieces of data so I think if the drive is the culprit, this new one won't be. The random read and write is on a nice MB/s rate also.
I get that during transferring of too many torrents at a time that it might cause Qbittorrent to halt the uploads until it's done since the drive is likely running at it's max speed, although my OS says only MB/s so it really isn't. But even if moving mass files bottle-necks it, I would think a download of only 20 MB/s wouldn't kill my upload / cause it to jitter to 0 and back up to max repeatedly. Another interesting detail, now that some of the moving torrents have finished, my drive is actually reading at MB/s unlike the ~MB/s it was doing earlier today.
Is there some known issue with Qbittorrent where it can't handle doing many torrents at a time for moving files? And when downloading, it can't keep up with reads for upload? Or is there a setting I'm missing that could help prevent Qbit from prioritizing other tasks over upload? I realize most users normally only care about download but I really want to prioritize my upload since the speed is slow as it is.
Also, there is another drive that seeds some of the torrents and is not currently active doing anything so that's part of why I think it's the program and not the drive. Otherwise, you'd think those drives could be uploading right now since they aren't doing anything. And yes, there is always someone who wants data off those 10 TB drives. They are normally uploading when there isn't download/move activity in qbittorrent.
