Why is the murmur slower than the built-in MD5 / SHA1 method

I just tried C # hash hash port ...

However, I am very disappointed in its performance. It seems to be slower than the Cute MD5 / SHA1 computeHash built-in method.

Debug mode is OK, and noise in this mode is faster. If you switch to Release mode, it will be slower than SHA1 or MD5.

I found the reason it should be installed on x64 or anycpu instead of x86

here is the test result.
