my tcmalloc test tcmalloc is 10x slow than glibc! Appreciate it for you advise!

Test code was built with bazel, and the result:

glibc run-time 273900440ns
tcmalloc run-time 3360949905 ns

tcmalloc is 10+ slow than glibc, it's so confusing for me! Is anything wrong with my build?

Thank you very much for your help！！

test code:

#include <iostream>
#include <chrono>

class A {
        public:
                A():a(32){}
        int64_t a;
};
void test() {
    A *cs = new A();
    delete cs;
}
int main() {

        auto start_time = std::chrono::high_resolution_clock::now();

        for (int i = 0; i < 10000000; i++) {
                test();
        }

        auto end_time = std::chrono::high_resolution_clock::now();
        auto duration = std::chrono::duration_cast<std::chrono::nanoseconds>(end_time - start_time);
        std::cout << "time " << duration.count() << std::endl;

    return 0;
}
