Because the JVM takes another tradeoff against Go and Rust: it has a runtime interpreter+JIT, which causes even more performance overhead than Go's GC let alone Rust which - at runtime - is effectively a zero-cost abstraction over C and jemalloc.

The JVM GCs generally have much lower overhead than Go's does. Go imposes enormous collection costs on apps to try and drive latency so low. This is widely acknowledged in discussions of the various GC tradeoffs.

The GCs alone? Yes. The rest of their respective runtime architectures? Highly doubtful. As GC-dependent as Go may be, it still does end up as native code.

But frankly, comparing Go to Java when things like Rust exist ... seems analogous to comparing the z80 to the AVR when 32-bit ARM cores exist.

Offtopic/meta: for some reason your post was dead. The comment at the end is kind of pointless and flamey, Rust isn't that good, but doesn't seem to justify a post kill. I vouched for you to bring it back.
