DL speed randomly collapses #13702
Comments
But did you try another torrent client? |
Just tried it with transmission in the same vm using the same port... |
I just downloaded 2 torrents with a size of around 6 GB each simultaneously in qBittorrent and Transmission. Transmission finishes both torrents without an issues and decent speeds. It is definitely not an issue with... my operating system installation, my vpn tunnel setup, my vpn provider or my network. |
I am not sure if this helps but here are my two cents,. |
I think i have the same issue, i have like 30 torrents download at 90mb/s for 15 minutes constantly, then drops to 40mb/s for like 2 or 3 minutes and then goes back again to full speed |
What happens in torrent is that, it caches whatever you download (@ 90 mb/s) and then tries to slowly move this cache to the disk, if your drive is slow (read/write) then the cache will be full after the 2-3 minutes and then the speed of download will almost be equal to the speed of the writing,, then when some part of cache is cleared, the speed will increase again, when the cache is full the speed will drop, it could be one of the following |
Closing this as this was reported on a very old version. If you can still reproduce it with latest version please comment to re-open the thread or create a new thread. |
qBittorrent version and Operating System
Linux DOWNLOAD-VM 4.19.0-12-amd64 #1 SMP Debian 4.19.152-1 (2020-10-18) x86_64 GNU/Linux
qBittorrent v4.2.0 and v4.3.0
Flatpak v1.2.5-0+deb10u1
If on linux, libtorrent-rasterbar and Qt version
latest flatpak stable package of qBittorrent
What is the problem
As the title says I am having some trouble with my DL speeds in qBittorrent (v4.3.0) running alongside pyLoad in my download vm. The whole traffic of that vm gets tunnelled trough my vpn provider. A set a static torrent port in qBittorrent and forwarded that port at my vpn provider and in my firewall to the download-vm. The port also gets recognized as open. Both qBittorrent and pyLoad download to my nas with an smb share that is mounted to a local directory.
Sometimes my torrent files run just fine at full speed (~6 MB/s). But most of the time the download starts, goes to full speed and then all of a sudden the speed goes down to around 10 KB/s. I doesn't happen at a specific DL size, time or percentage.
What makes me believe that it has to do with just qBittorrent is the fact that pyLoad and a speedtest run at full speed while the torrent speed is slow.
After restarting qBittorrent, while the torrents are still running, the speed goes back to normal.
What is the expected behavior
full speed
Steps to reproduce
none
Extra info(if any)
It doesn't have to do anything with the flatpak package of qBittorrent.
I tested the flatpak version and the "apt" version of qBittorrent. Both have the same error.
qBittorrent.conf
