"High" CPU usage at idle with official Docker setup

[xnyo]

Hello, I tried setting up rudderstack with docker following the official documentation (https://docs.rudderstack.com/get-started/installing-and-setting-up-rudderstack/docker)
The only change I made to the docker-compose file was changing WORKSPACE_TOKEN with the correct value.
The server starts and the events get dispatched correctly, however the CPU usage at idle, with no events whatsoever is about 20-25% on my machine (i7-8550U 3.9GHz). I got similar results on a different machine too. I am running Linux and Docker 19.03.12.
All containers are on the "latest" tag, like in the provided docker-compose file (rudderlabs/rudder-server's hash is b0cf66d1817c and rudderlabs/rudder-transformer's hash is 4bb81602b25f)
Is this normal? If so, is there a way to reduce the CPU usage by tweaking the config file?

Thanks in advance!

Hi
Sorry for the late response.

Please set the following environment variables. They will bring down the CPU usage drastically.
RSERVER_PROCESSOR_FIXED_LOOP_SLEEP_IN_MS
RSERVER_ROUTER_FIXED_LOOP_SLEEP_IN_MS

You can set their value to, say 2000, for 2 secs sleep.

Thanks.
