RustFFT performs best on small inputs that fit entirely into the L2 cache, while PhastFT is optimized for large input sizes common in scientific computing. +PhastFT also uses 2x less memory, which is important for processing large datasets. + RustFFT made the choice to work on stable Rust compiler at the cost of `unsafe` code, while PhastFT contains no `unsafe` blocks but requires a nightly build of Rust compiler to access the Portable SIMD API.
