As the owner of a somewhat popular language, I checked to see if there's an extension available (there is!) as we publish a language server.

One thing I noticed in the implementation is that it looks like it is using stdin/stdout for the JSONRPC inter-process communication, rather than named pipes or sockets. VSCode uses named pipes. I wouldn't be at all surprised if that's a significant bottleneck - I'm about to file a bug.

EDIT - commented on the tsserver thread here: https://github.com/zed-industries/zed/issues/18698#issuecomm...
