Odd Speed issues, downloads/uploads fast for seconds then stalls... then starts again

Post by xxyzne »

Hi All,

I have a very odd problem I am trying to solve.

I moved away from Torrent and am setting up qbittorrent for the first time on a new server. At the same time, I changed my internet connection and router.

I am running
- 1gbps connection
- Ubuntu 23.04
- qBittorrent v4.5.2 on docker
- Port forwarded from the router, not using Upnp.
- Running on MergerFS filesystem (with the correct mmap settings)

I am see very unusual activity. When i start a torrent, i see it download at high speeds 80MB/s+ for maybe 20-30 seconds, then it suddenly drops to almost 0mbps. I see this happen on the upload and download. It will constantly fluctuate.

I am trying to figure out what is going on but i have exhausted all my t-shooting.. which is
- change ports, ensured port is accesiable
- changed several settings in qbittorrent, nothing helped.
- disabled all torrent queuing and rate limits in qbittorrent.
- upped the number of connections per torrent etc..
- disabled all firewalls, AV's etc.
- restarted router, server.. tried a different version of qbittorrent.

Does anyone have any suggestions on what i can t-shoot or what might be going on?

thanks!
