Fine Tunning Note

The Cache size should be set to around 1/4 of the machine total available ram. In case you opt for qBittorrent 4.3.x, you need to take account into memory leakage and set it to 1/8.
aio_threads default setting is 4 and should be good for HDD. For SSD or even NVMe server, you might consider increase it to 8 or even 16.
- For qBittorrent 4.3.x - 4.6.x you can change it in the advance setting tab.
- For qBittorrent 4.1.x, you can set it in /home/$username/.config/qBittorrent/qBittorrent.conf by adding Session\AsyncIOThreadsCount=8 under [BitTorrent] section
  - Please shut down qBittorrent before the editing
- For Deluge, you can install ltconfig and edit through the plugins
  - aio_threads=8
send_buffer_low_watermark, send_buffer_watermark & send_buffer_watermark_factor can be set to a lower value if you are running on a machine with poor I/O.
- For qBittorrent 4.3.x you can change it in the advance setting tab.
- For qBittorrent 4.1.x, you can set it in /home/$username/.config/qBittorrent/qBittorrent.conf by adding Session\SendBufferWatermark=5120,Session\SendBufferLowWatermark=1024andSession\SendBufferWatermarkFactor=150 under [BitTorrent] section
  - Please shut down qBittorrent before the editing
- For Deluge, you can install ltconfig and edit through the plugins
  - send_buffer_low_watermark=1048576
  - send_buffer_watermark=5242880
  - send_buffer_watermark_factor=150
tick_internal default setting is 100 which can be too high for some weaker CPU. Consider changing it to 250 or 500.
- Sadly there is no way to change this setting in qBittorrent
- For Deluge, you can install ltconfig and edit through the plugins
  - tick_interval=250
A little bit more fine tunning notes can also be found in /etc/sysctl.conf
For file system, I highly recommend using XFS
