Hi, ahash allows to use HW acceleration, but usually it comes at a cost of additional HW related configuration overhead, such as configuring hash module, DMA, etc. For that reason hashing small chucks of data is faster doing it with shash (CPU) rather than HW acceleration. I measured long time ago on omap-sham driver but cannot recall any data. Does anyone have any experience under what data size it is still better to use shash?
