 Each server has different limits to configure. The `soft_limit` is the number of parallel active requests where a server starts to slow down. The `hard_limit` is where a server starts giving rate limits or other errors.

+2. Copy `./config/example.toml` to `./config/development.toml` and change settings to match your setup.
