I did some profiling with Valgrind yesterday. I don't have a very good knowledge currently of the workings `memory` but there I saw as well that some of the lines in the code related to `MutableBuffer::extend_from_slice` in terms of instruction cycles as they are called a lot in the code / kernels. I think a few "micro optimizations" are possible there. It makes sense to me that switching to `Vec<u8>` benefits from it being optimized/benchmarked already extremely well. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
