I haven't directly measured any throughput or latency numbers. I know it is relatively fast, but I know it is not as seamless as I would like.

Currently, for WASM to call any imported function, its arguments have to be formatted in a particular way that is specified by the wasm-c-api. Then it can invoke the imported function. Only after that can the arguments be translated back into the native calling convention in order to call the real native function. I don't know how that compares to node-ffi and JNI, but I imagine its not as slow.

I have a piece of documentation I need to write that will explain how calling native libraries works from Onyx, so that should be able to go into more detail.
