I added a benchmark test (Apple M5) and on average I'm seeing 10ms overhead. I added a benchmark section to the repo as well https://github.com/afshinm/zerobox?tab=readme-ov-file#perfor...

Also, I'm literally wrapping Claude with zerobox now! No latency issues at all.

Wasm sandboxes are fast for pure compute but get painful the moment LLM code needs filesystem access or subprocess spawning. And it will, constantly. Containers with seccomp filters give you near-native speed and way broader syscall support — overhead is basically startup time (~2s cold, sub-second warm). For anything IO-heavy it's not even close. We're doing throwaway containers at https://cyqle.in if anyone's curious.

I will run the same benchmark test on wasm sandboxes just to be able to compare it with Zerobox. I will share the results tomorrow.

Here is the video, running Claude with Zerobox, you can see the latency, etc. https://www.youtube.com/watch?v=xzsGsSsx0OI
