Is this "years of research" the reason why most Electron apps still start slower than - for example - IntelliJ IDEA, which is written in Java and Swing?

Modern Java has Coordinated Restore at Checkpoint (CRaC) as well as ways to compile it to native binaries that can start very fast (GraalVM & Substrate VM). The former has the benefit of a JIT as well!

Have you used any of these? I’m looking for ways to speed up start time of JVM, but almost options I’ve seen so far are “experimental” and not sure best route to take. For example was sad to see ahead of time compile being removed from JDK.

Just imagine if those years of research went into a good language instead. Instead of expending a huge amount of effort making an inherently slow language perform reasonably, we could have taken a reasonable language like Rust and made it so good it would legitimately push computing forward.

And then all you web devs could still compile rust to wasm. wasm is already faster than JS anyway. JS was a mistake.
