I have the same problem:
qBittorrent: 4.4.2
CPU: Intel(R) Celeron(R) CPU N3160 (4 cores)
RAM: 4GB
Operating system: Ubuntu Linux 18.04
Docker image: linuxserver/qbittorrent:latest

With 127 torrents but no active torrents CPU usage stays at 30% all the time.

Also seeing this on my Synology NAS (Celeron J3550/8gb RAM) after setting it up in Docker. Load averages for the NAS are over 2.0 with qBT running, sits at 0.4 without qBT running.

I've only go 12 torrents in there, with a cap of 8 active (3 down, 5 up). Have tweaked my connection count down to 200 to get fewer spikes, but it's still pretty bad.

Got a feeling it could be something to do with disk caching as it also uses a lot of memory and [kswapd0] process is also frequently high when qBT is running. Imagine it can be solved with some advanced libtorrent settings, but not sure where to look for best settings.

在 Docker 中设置后，在我的 Synology NAS (Celeron J3550/8gb RAM) 上也看到了这一点。运行 qBT 时 NAS 的平均负载超过 2.0，未运行 qBT 时为 0.4。

我在那里只下载了 12 个种子，活跃的上限为 8 个（3 个向下，5 个向上）。已将我的连接计数调整为 200 以减少尖峰，但这仍然很糟糕。

感觉这可能与磁盘缓存有关，因为它也使用大量内存，并且[kswapd0]在 qBT 运行时进程也经常很高。想象一下，它可以通过一些高级libtorrent设置来解决，但不确定在哪里寻找最佳设置。

You can try version 4.3.9. Trust me, it will improve a lot

Have you ever fixed this? I'm using hotio's legacy (4.3.9) container and I'm having the same issue.

I see. Did ypu have the exact same symptoms as I did? Is there a disadvantage if I don't use 4.3.9 though?

@kevindd992002 Talking only in from my experience, no disadvantages using >= 4.4 versions, the main feature is support for v2 torrents.
My rule of thumb is if the new version works equal or better, upgrade, if there are disadvantages in your daily use, skip the version.
The platform I use is Raspberry Pi 4, I do not have experience with Synology NAS.
If you keep having issues I recommend to open an issue specifically for your case.

Gotcha. I just realized that the 4.3.9 container I'm using still has libtorrent 1.2. So I'm using the good version of libtorrent. Do you mind sending me over your config (including advanced settings)?

Oh and what are "v2 torrents"?

I fixed this using a version that uses libtorrent 1.x, in my case I use the image from linuxserver qBittorrent with libtorrentv1 in the tag

Talking only in from my experience, no disadvantages using >= 4.4 versions, the main feature is support for v2 torrents.

FYI, libtorrent-1.2 based builds don't support v2 torrents.

Yes. That's what @kanedauy was implying in his post. But is that really a loss?

I think still not. It is unlikely that there are currently quite a lot of pure v2 torrents in the wild.
