FFTW is typically faster than other publically-available FFT implementations, and is even competitive with vendor-tuned libraries. -There are several machine-dependent optimizations that can be enabled in order -to generate SIMD code; take a look in fftw.SlackBuild to enable them. +By default non-portable binaries will be created.
