Description

We have a large monorepo (50+ Maven projects). We want to use VS Code dev containers for local development, but it takes forever to start up (i.e., import projects, etc.).

For context, our laptops are running Windows 11 and we're using Podman Desktop with WSL as the container host. We are using volumes rather than the default bind mount, which has improved performance. We are building the images locally which also decreases the time it takes to create or rebuild a dev container.

On a fresh volume the initial import takes a very long time. Maybe 2 hours? Just a guess. Reloading the window or rebuilding the container also takes a long time. Maybe 30 minutes - 1 hour?

Is this expected? Is there anything we can do to improve performance?
