Performance of Devicescript #175

How fast will the compiled code run in comparison to native C/C++ ?

mmoskal commented 1 year ago

Here is a paper we did on a previous project that was compiling TS to native ARM code.

DeviceScript is using a VM interpreter which is slower (but portable - we currently run on RISC-V, ARM, Xtensa, x86, WASM, and probably much more).

For low level manipulations I would guess anything between 10x-100x.
