wow that wasmer thing is _SLOW_.. we are talking about 57x time slow! (granted most of this is likely startup delay). Here is a random benchmark with warmed-up

wow that wasmer thing is _SLOW_.. we are talking about 57x time slow! (granted most of this is likely startup delay). Here is a random benchmark with warmed-up cache: $ time cat /var/lib/dpkg/status | wasmer run syrusakbary/pypipe@0.1.0 -- 'i, line.upper()' | wc -l 39175 real 0m5.761s user 1m15.071s sys 0m4.838s vs regular python: $ time cat /var/lib/dpkg/status | python3 pypipe.py 'i, line.upper()' | wc -l 39175 real 0m0.107s user 0m0.096s sys 0m0.026s and the wasmer install procedure.. not a deb file in sight, adds itself to ~/.bashrc (of course...) and apparently requires two environment variables to even work. Compare this to OP's instructions: (1) check out the repo (2) execute the file directly. Not sure why would anyone want wasmer for simple command like tools like those.
