Research direction

Start by locating the wasm transport layer and tracing how data is marshalled between JavaScript and C++. Measure temporary buffer allocations and data copies first; done means unnecessary allocations or copies are reduced without changing transport behavior.

Description

enhancement

There are opportunities to improve the performance of the wasm transport layer. It necessarily includes marshalling of data between JavaScript and C++, but I think some of this can be improved as there are some unnecessary allocations of temporary buffers where we can probably just reuse the same buffer, and we may well be doing more copies of data than are strictly necessary.
