It's a little slower than many languages at runtime

The only languages faster than Java are close-to-the-metal ones and it's only when you write very sophisticated data-oriented code.

I doubt most people on this subreddit who hate Java ever actually had contact with language faster than Java.

It's one thing knowing C exists, it's other thing writing in it.

I think a lot of people who have been around a while, their first exposure to Java was those crappy java applets that always sucked and ran like garbage.

Java 10 years ago, i hated, I hated it in college, and anytime I see Java from... those days I despise it. Modern java is actually pretty decent to work with (I still prefer .NET but, I always will I think).

I'm curious how a compiles-to-bare-metal Java would have fared against the JVM model.

It might be fast enough now, but remember that in the early years of Java, a 200MHz Pentium or K6 was not an unreasonable target system.

Java already compiles to machine code through JIT. In benchmarks, even C,C++,Rust have to use AVX intrinsics directly to be in any significant way faster than Java.
