Seedbox Installation Script

!!! This script is only intended to run on freshly installed Debian 10

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 Optimized 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. (Or even on a unmetered network, since this is boarderline DDoS already)

I am not actively managing this script, please debug it yourself

Usage

bash Install.sh <username> <password> <Cache Size(unit:GiB)>

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 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
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
