And arguably it beats the performance of C/C++/Rust when written without proper care: https://blog.codinghorror.com/on-managed-code-performance-ag...

The big take-away I got from this (admittedly quite old now) experiment is that getting advertised performance out of unmanaged languages for typical real-world (i.e., non-benchmark) tasks often requires a lot more care than people really account for. Nowadays memory dominates performance more so than CPU, and the combination of a JIT compiler and a good generational, compacting garbage collector - like C# and Java developers typically enjoy - often does a better job of turning idiomatic, non-hand-optimized code into something that minimizes walks of shame to the RAM chips.
