1. Pre-allocated disk space for the added torrents, this limits fragmentation and also makes sure if you use a cache drive or a feeder disk that the space is available.
Do not set Pre-allocated disk space if you are using ZFS as your filesystem as ZFS [does not support fallocate](https://github.com/openzfs/zfs/issues/326){:target="_blank" rel="noopener noreferrer"}
1. If you enable this, your incomplete downloads will be placed in this directory until completed. This could be useful if you want your downloads to use a separate SSD/Feeder disk[^1], but this also results in extra unnecessary moves or in worse cases a slower and more I/O intensive copy + delete.
1. Your port used for incoming connections, this is the port you opened in your router/firewall or port forwarded at your VPN provider to make sure you're connectable.
**Suggested: `For a home connection that you use with others it's best practice to set the upload/download rate to about 70-80% of your maximum upload/download speed.`**
1. These settings are mainly used for public trackers (and should be enabled for them) and not for private trackers, decent private trackers use a private flag where they ignore these settings.
1. Recommended setting `Allow encryption` rather than enforcing it allows more peers to connect and is recommended on underpowered systems as it will allow for lower overhead.
1. Anonymous mode hides clients (qBittorrent) fingerprint from the peer-ID, sets the ‘User-Agent’ to Null and it doesn’t share your IP-address directly with trackers (though peers will still see your IP address). If using private trackers, it's recommended to `disable` this. I also got reports from people who are using this that they had worse speeds.
Personally, I recommend using the seeding goals in your Starr Apps indexer settings (enable advanced), or use [qBit Manage](/Downloaders/qBittorrent/3rd-party-tools/#qbit-manage){:target="_blank" rel="noopener noreferrer"}
