Comparing the C FFI overhead on various languages

I developed a terminal emulator, file manager and text editor Deodar 8 years ago in JavaScript/V8 with native C++ calls, it worked but I was extremely disappointed by speed, it felt so slow like you need to do a passport control each time you call a C++ function.

The official solutions, node-ffi and node-ffi-napi, are extremely slow, with an overhead hundred of times higher than it should be. I don't know what they do to be so slow.

I'm making my own FFI module for Node.js, Koffi, as a much faster alternative. You can see some benchmark here, to compare with node-ffi-napi: https://www.npmjs.com/package/koffi#benchmarks

An interesting alternative would be to not have any FFI and to use transparent polyglot interop between javascript and c++ via GraalJs /sulong

Oh nice, with a Norton Commander-alike terminal UI.

I'm not sure where the use of Yacc ends and https://github.com/exebook/elfu begins in the .yy files (which are sprinkled with very algebraic-looking Unicode throughout). The Pascal-like class definitions may be defined in https://github.com/exebook/intervision.

Very interesting project.

Probably butter smooth after eight years of V8 development and Moore's Law (well whatever passes for it now).

Probably not since single threaded improvement has barely advanced over the last 8 years, and JS/V8 are still in a single threaded world that stopped existing a decade ago.
