Performance Service

Multi-purpose microservice for all things performance.

It features:

• A performance calculator (compliant with USSR).
• A mass score recalculator.

Usage

Requirements

• The Rust toolchain installed (mainly cargo) for compilation.

Compilation

To compile it, use the following command if you want simply use it for testing. This will reduce compile times.

cargo build

This will create a binary in performance-service/target/debug.

Or if you want a production deployment, use this one. It will take longer (~1 minute excluding libraries) but produce a significantly faster binary.

cargo build --release

This will create a binary in performance-service/target/release.

Deployment

Components

The performance service features multiple componenets to cover most usecases. These can be selected through the app-component flag as so: ./performance-service --app-component=thing.

Component	Usage
api	Runs a web API for performance calculations. Use when running a score server such as USSR
deploy	A console interface for recalculating the whole server with the current PP system. Handles stats and score overwrite.
mass_recalc	Internal undocumented rework testing tool.
recalc	Recalculates a single user.

Configuration

There are other flags available for advanced users and configuration. These may also be set through creating a copy of the .env.example file and naming it .env.

Flag	Purpose
api_port	The port at which the api component should run. Has no impact elsewhere.
mysql_user	A MySQL user with read-write access to scores and users.
mysql_password	The password for the MySQL user.
mysql_host	The host of the MySQL server.
mysql_port	The port of the MySQL server.
mysql_database	The RealistikOsu database.
redis_user	The Redis user with access to global readerboards (leave empty if no authentification is required).
redis_password	The password for the Redis user.
redis_host	The host of the Redis server used for global leaderboards.
redis_port	The port of the Redis server.
redis_db	The index of the Redis database.
beatmaps_path	The location at which .osu files for beatmaps should be stored. For optimum performance, use the same directory that your score server uses.
