Hi @Beherasaptami. By default sanic will listen to the process using only 1 CPU. By increasing the number of workers you can enable your application to use more CPUs and therefore work faster.

You can configure this parameter by setting the environmental variable `SANIC_WORKERS` to a different number than 1. For example, to set it to 2 you can run in your command line:

`export SANIC_WORKERS=2`

@juste_petr on the above - should this number be tuned up for production and load testing?

Does it apply to all channels? Websocket, http, slack, twillio, etc?
