Maximum number of torrents qBT can handle?

Post by Zaphod414 »

The last time I used qBittorrent many years ago now, it would get real flaky with a large number of torrents running. Back then a large number of torrents was like 100 or more. These days I might have 300 - 500 or more in the UI at a time. Would this still be an issue for qBittorrent to handle stably, or is that still an ongoing problem with it?

I'm looking to replace Deluge with something that's just as mature but is still being more actively developed. I have Deluge running on a Linux box in a Docker container, and I access it from a Windows PC using the native UI or the web UI. I would like to have the same setup for qBT with the guts running in a Linux Docker container and the UI running on Windows. I gather this is possible from the available docs, but I wouldn't mind hearing from others in the community running a similar setup to see what your experiences have been.

I ran qBittorrent with 30.000+ torrents about 2 years ago with 0 issues.
I think it depends on your hardware, the storage, etc.

You can also just run multiple instances and split up the load a bit.

I just moved to a new rig, AMD Ryzen 7 5800X with 64GBs of memory, from a old rig, FX-8350 with 32GBs of memory. I have over 4,000 torrents here. Even on my old system, the CPU usage was around 3 to 4% for torrent software. On my new rig, it isn't even 1% except for the occasional blip or when first starting up.

The biggest consistent slowdown on my system, the speed of the hard drives. I have three hard drives using LVM that total just over 41TBs. They at about 76% full. Even with data spread over more than one drive, the torrent transfer data at times is as fast as the drives can supply the data. Sometimes my VPN will slow things down a little, peak times of internet usage. I have fiber internet here.

I'm with Peter tho. If you have fast enough CPU and enough memory, that's about the only limit other than storage. I suspect if I ran torrent software and little else on my old rig, I could have tens of thousands of torrents. The CPU may be busy at times but likely still nowhere near its limit. A newer rig like my current one, I'd hate to guess but wouldn't be surprised if over 100,000 were possible.

Keep in mind, Linux user here. I use Gentoo. This is the Linux section of the forums tho.

Hope that helps.

Good to know, guys. Thanks for the feedback. I made the switch. Time will tell now.
