alt Hacker NewsMicrosandbox claims to start faster than docker, and it is isolated from the host, and to work with OCI. Why would I still want to use docker? The only reason I can imagine is that I actually want to be able to dynamically share resources between containers instead of dividing up VMs a priori.
Ah, the significant compute overhead: https://josecastillolema.github.io/podman-wasm-libkrun/. Much more cpu and ram usage at worse performance.

The performance difference in that post is due to wasm, not the container runtime, which is also stated at the end of the post.

Starting faster than a container will need evidence since starting a container on Linux is basically instant.

This has been a big pain point me with various VM solutions I’ve tried. Having to allocate say 8GB to a sandbox, and a) having that RAM eaten up when I’m not using it and b) only having 8GB when I am using kinda sucks.
Yes, I could stop the sandboxes when I’m not using them, but that also kinda sucks.
