Ran gVisor on a Pi 4 cluster for home IoT sandboxing. Memory overhead is real—about 120MB per sandbox vs 15MB for raw containers. On 4GB boards that limits you to ~25 isolated services before OOM kicks in. Also, syscall拦截 adds 30-40% CPU overhead on ARM. Works fine for untrusted Python scripts, but I wouldn’t run anything compute-heavy.

Wouldn’t compute workloads be fine as they should not be syscall bound?

yeap -- compute would be nearly the same. I suspect you need some kind of I/O to make your compute useful (get input for the computation / produce output etc.) so, still, this would have a negative effect overall.
