apache - Why does a single PHP request take up much less memory under Linux than under Win?

Usually an application written in the thinkphp framework under apache-win32 takes up about 1-2m of memory per request. When running on apache under Linux, it drops to more than 200k per request. Why is this gap ten times? Does anyone know the difference in the details of the underlying principles?

Every software in Linux takes up much less memory than Windows.
