In this case it's literally the LSP and maybe JetBrains have a different way of doing all of this more efficiently or it's just that many LSPs are not written in the most efficient language. We're beginning to see more Javascript tooling that are written in other languages such as Go and Rust that just blow away existing tooling in terms of performance. Look up on esbuild/swc. Last I heard JetBrains is also looking into adopting LSP so maybe we could even pay for JetBrains LSP to use with VSCode some day
