This is not correct. You are using WebVM here, not BrowserPod.

WebVM is based on x86 emulation and JIT compilation, which at this time lowers vector instructions as scalar. This explains the slowdowns you observe. WebVM is still much faster than v86 in most cases.

BrowserPod is based on a pure WebAssembly kernel and WebAssembly payload. Performance is close to native speed.

I see. I thought they were the same and https://vitedemo.browserpod.io/ failed to load, so I was not able to test there.

Demo works as expected for me, please share information if possible or join our Discord for further help: https://discord.leaningtech.com

I dug a bit deeper. The cause was that navigator.storage.getDirectory() is not available in Firefox private browsing mode.

The performance is pretty amazing. fib(35) runs in 60ms, compared to 65ms in NodeJS on Desktop.

But I can't find a shell. Is there only support for NodeJS at the moment?

Only node is supported as of version 1.1, but the next version is fully focused on command line tooling (git, bash, ssh, grep, ...).

Also, could I ask you to quickly edit your previous comment to clarify you were benchmarking against the older project?

Unfortunately, that comment can not be edited anymore. Maybe @dang can change it or remove the comment chain. I am fine with both.
