Improving FFT performance in Python

Question

What is the fastest FFT implementation in Python?

It seems numpy.fft and scipy.fftpack both are based on fftpack, and not FFTW. Is fftpack as fast as FFTW? What abou

Answer 1

The pyFFTW3 package is inferior compared to the pyFFTW library, at least implementation wise. Since they both wrap the FFTW3 library I guess speed should be the same.
