I think you're right. I got confused because he talks about compiling to WASM; I'm not knowledgeable about WASM but a language server is an entirely separate process, which means you can compile your Rust to native x86 or whatever you want. I assume Rust compiled to native machine code is faster than WASM? I guess the one advantage of WASM in that case is that you don't have to compile the language server for every platform the extension runs on. (In my case, I compile the language server for x86 Linux and Windows.)
