This script does not guarantee performance increase and might cause some serious bugs to your machine. The idiot that write this script literally has zero coding knowledge and probably fuck up somewhere. Please use with cautions
The Tweaked BBR would increase packet retransmission rate and waste your bandwidth. On 10Gbps network, the waste is around 30% of your acutal upload ammount and around 10% on a 1Gbps. Please use with caution if you are on a metered network.
Support for Debian 11 is probably the last update, I am not actively managing this script, please debug it yourself

-
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 you can change it in the advance setting tab.
- For qBittorrent 4.1.x, you can set it in /home/$username/.config/qBittorrent/qBittorrent.conf by adding
Session\AsyncIOThreadsCount=8under [BitTorrent] section- Please shut down qBittorrent before the editing
- For Deluge, you can install ltconfig and edit through the plugins
- aio_threads=8
-
send_buffer_low_watermark, send_buffer_watermark & send_buffer_watermark_factor can be set to a lower value if you are running on a machine with poor I/O.
- For qBittorrent 4.3.x you can change it in the advance setting tab.
- For qBittorrent 4.1.x, you can set it in /home/$username/.config/qBittorrent/qBittorrent.conf by adding
Session\SendBufferWatermark=5120,Session\SendBufferLowWatermark=1024andSession\SendBufferWatermarkFactor=150under [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
-
TCP buffer size in /etc/sysctl.conf could be a little bit too high if you machine is low on ram. Please change it accordingly.
- A little bit more fine tunning notes can also be found in /etc/sysctl.conf
-
For file system, I highly recommend using XFS
