It’s worth noting explicitly what others have said - if you are doing what you describe, you are running your Linux containers under QEMU. The performance of this will be terrible; there is likely little room for optimisation and you should not expect this to get any faster in the future. Using aarch64 containers changes the game entirely. Common base images like Ubuntu are already multiarch so will just work out of the box. But this has obvious downsides and won’t be a suitable solution for everyone.
