the JS layer is slow, indeed, but it shouldn't be that much slower that it meaningfully impacts frontend apps
replyA demonstration of that by the creator of Leptos:
That's fair and makes sense. In my case it was just a regular web app where the only reason for it being in Rust was that I like the language.
replydid you profile what made it so slow specifically? sounds waaaaay worse than I would expect
replyI did. I don't remember the specifics too well but a lot of it was cold starts. So just crunching the massive wasm binary was a big part of it. Otherwise it was the matchit library and js interop marshalling taking the rest of the time.
replyedit: and it cold started quite often. Even with sustained traffic from the same source it would cold start every few requests.
