Tyto is an open source BitTorrent tracker written in Rust. It aims to be safe, performant, and rock-solid.

Why?

Tyto was created to facilitate the distribution of media through the BitTorrent protocol. Many of the popular tracker software available has not been updated in more than a decade. Many aspects that were "nice-to-have" at the time, e.g. IPv6 support, multithreading, etc., have become quite necessary at the scale at which modern deployments operate. Tyto implements many of the newest official standards and de facto extensions in order to create a robust and performant distibution system that can be used to serve many swarms with minimal downtime.

Features

• [ ] Configuration hot-reloading
• [x] Global metrics
• [x] IPv4 and IPv6 support
• [ ] Private tracker support
• [ ] Storage-agnostic backend
• [ ] Swarm statistics

Usage

Building

Tyto requires the latest stable version of Rust.

$ git clone git@github.com:adcrn/tyto.git
$ cd tyto

Edit config.toml to the desired configuration, and then build the program. Testing is also available.

$ cargo test
$ cargo build --release

Running

Make sure that the storage backend and path have been correctly added to the configuration before starting the program. Then start it up! The -c flag is also available to provide an alternate path to a configuration file.

$ ./target/release/tyto

Performance

The tracker makes heavy use of async/await and does its best to reduce excessive allocation of objects. The following stats were achieved on a 2017 MacBook Pro:

❯ wrk -t3 -c90 -d1m -s wrk_load_test.lua http://localhost:6666
Running 1m test @ http://localhost:6666
  3 threads and 90 connections
  Thread Stats   Avg      Stdev     Max   +/- Stdev
    Latency     3.89ms  815.50us  22.07ms   97.30%
    Req/Sec     7.79k   462.48     8.76k    81.17%
  1395683 requests in 1.00m, 512.99MB read
Requests/sec:  23258.34
Transfer/sec:      8.55MB

The stress-testing procedure can be found in wrk_load_test.lua and makes use of the wrk program.
