Jinc has to be slower than other linear resamplers because due to how it works (can't be split into 2 separate passes) it has to read and process more source pixels. E.g. compared to Lanczos3, Jinc3 has to read and process 4x as many source pixels.

One thing to keep in mind is that NNEDI3 can only do exact 2x enlargements while Jinc can handle any up- and downscale factor you want.
