Benchmark

Run pytest ./benchmark.py -s to compare the performance of a2wsgi and uvicorn.middleware.wsgi.WSGIMiddleware / asgiref.wsgi.WsgiToAsgi.

Why a2wsgi

The performance of uvicorn-WSGIMiddleware is higher than a2wsgi. However, when dealing with large file uploads, it is easy to cause insufficient memory uvicorn/issue#371. a2wsgi uses synchronous signals and asynchronous signals to regulate the pace of reading data, thus solving this problem.

With the help of ASGIMiddleware, you can turn any ASGI program into a WSGI program. This is very effective when deploying starlette, FastAPI, responder, index.py to Serverless.
