Why the speeds of multithreading pyfftw on window and linux are different?

The "threads" argument of pyfftw can induce multithreading parallel computing of FFT on the 2D matrix, and I tested the speeds of pyfftw with different parallel threads on 256*256 matrix, multithreading pyfftw is slower than the single-thread one on ubuntu of VMWare, and is faster than single-thread one on windows.

I don't know where the problem is.
