bionic is the "libc" of android, there are hardware optimized memcpy/memset and a few others for cortex-a9 and/or armv7-a, but also others specifically for krait, using those instead of stock bionic versions perform the same job a lot better than the more generic versions in aosp.
That affects memory throughput significantly and anything where you move data and need memory throughput using those functions will benefit from it.
there are other (math) functions that can be optimized more for the particular hardware
