Erlang performance in a container?

[Gerhard Lazu]

Hi,

Does Erlang has the same performance inside a container?

Yes, but only if you respect
https://adoptingerlang.org/docs/production/kubernetes/#container-resources
& don't use the default bridge network.

1. Allocate dedicated CPUs to the Erlang VM running inside the container.
Match the number of Erlang VM schedulers to the number of dedicated CPUs
allocated to the container.
2. Configure the container to use the host network.

Hope this helps, Gerhard.
