FFT on CPU comparison

For SETI we use single precision (float) complex-complex and real 1D transforms, power of 2 sizes.
Other graphs are irrelevant to our usage pattern.
It seems IPPS is the winner overall. FFTW outplace is closest competitor.
Don't see FFTS (
https://github.com/anthonix/ffts
) in these charts (FFTS (
https://github.com/matszpk/native-boinc-for-android/tree/master/src/setiathome-7.0/ffts-vfp-prefix
) was used by Matszpk in his optimized MB7 build for Android ARM).
