Java vs Rust: which is better for performance-critical services?

The question is about Java .

Answer:

Rust generally wins on raw, predictable performance for latency-critical services, since it runs without a garbage collector and compiles straight to native machine code, but Java's JVM has closed much of that gap for typical backend workloads since virtual threads shipped in JDK 21.
