~20x slower for a naive recursive Fibonacci implementation in Python (1300 ms for fib(30) in this VM vs 65ms on bare metal. For comparison, CPython directly compiled to WASM without VM overhead does it in 140ms.)
~2500x slower for 1024x1024 matrix multiplication with NumPy (0.25 GFLOPS in VM vs 575 GFLOPS on bare metal).
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.
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?

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