Java is faster than the optimized Rust program

hi. at first, I was a Rust programmer and wrote some projects and one framework for it, after hearing about Dynamic compilation technology, JVM made it attractive for me, I wrote a program in rust with many optimization flags for the compiler to get the best performance, and wrote instance in java.

after warm-up time I saw an amazing performance from JVM, its a beast and can beat Rust in performance,

Rust result: 10,648 _ 6,678 _ 8,274
Java result: 8,661 _ 9,608 _ 6,302

Average of 12 times benchmark :
Rust: 9,948
Java: 8,693

Java Code :

public static void main(String[] args) {
        for (int q = 0; q < 1001; q++) {
            long tInit = System.nanoTime();

            ArrayList<CClass> arr = new ArrayList<CClass>(100);
            for (int i = 0; i < 100 ; i++) {
                arr.add(new CClass("fname", "lname", i % 30));
            }

            for (int i = 0; i < 100 ; i++) {
                CClass cls = arr.get(i);
                cls.validation();
            }

            if (q > 997) {
                System.out.println(System.nanoTime() - tInit);
            }
        }

    }

Rust Code :

fn main() {

    for _ in 0..3 {
        let now = std::time::Instant::now();
        // ===============================================
        
        let mut v = Vec::with_capacity(100);
        for i in 0..100 {
            v.push(Class::new("fname", "fname", i % 30));
        }

        for i in 0..100 {
            let cls = v.get(i).unwrap();
            cls.validation();
        }


        // ===============================================
        let now2 = std::time::Instant::now();
        println!("==> {}", now2.duration_since(now).as_nanos());
    }
}

i use some rust compiler flag for maximize performance:

[build]
rustflags=[“-C”, “target-cpu=native”]
[profile.dev]
lto = true
opt-level = 3

and the end , i love more and more JVM , java/Scala
great language, huge ecosystem, and amazing performance,
Alibaba, Linkedin, Twitter, Amazon using 80% of backend of all work on JVM,

this is not just for independent or productivity of JVM
its it for amazing performance and Amazing stability
