Adds the performance_tests/ directory. In the future we could use our own fake client software instead of rust-mc-bot. This would make it easier to run the tests. |

Performance Tests
Run the server
cargo r -r -p players
In a separate terminal, start rust-mc-bot. This command should connect 1000 clients to the server.
cargo r -r -- 127.0.0.1:25565 1000
# If rust-mc-bot was cloned in the performance_tests directory, do
cargo r -r -p rust-mc-bot -- 127.0.0.1:25565 1000
If the delta time is consistently >50ms, the server is running behind schedule.
Flamegraph
To start capturing a flamegraph, run the server like this:
CARGO_PROFILE_RELEASE_DEBUG=true cargo flamegraph -p players
Run rust-mc-bot as above, and then stop the server after a few seconds. Flamegraph will take its own sweet time to generate a flamegraph.svg in the current directory. You can then open that file in your internet browser of choice.
NOTE: The indiscriminate use of rayon in Valence appears to have made the flamegraph basically unreadable. This
situation should change soon.
