To follow up on this I should clarify what my questions are: 1) How much of a performance drop (when compared to AMD64 for example) should I expect when compiling to the WASM target?
2) Is there anything obvious I can do to counter any performance drops? And I suppose this is a non-Go question, but: 3) I know nothing about WASM beyond the bare minimum. How can I profile and understand the compiled WASM binary? Is it possible to use the pprof tool in some way?
