+By default, the application runs in single-threaded mode. This is not a solution for heavy loads. You can change this behavior by setting the appropriate environment variables "PUMA_THREADS" and "WORKERS". However, we do not recommend doing this. The application is not thread safe. If you need large loads, it is better to raise several application instances and set up load balancing between them.
