    I wonder how much of the performance will improve when compilers get better at RISC-V.

    It's been a long time since I could beat the compiler at optimizing assembly on x86, yet in the end merely unrolling a loop and keeping an eye on write-read stalls I managed to get a simple "multiply array by const" about 56% faster:

    And that's with hardware that doesn't even have vector instructions! I'd understand GCC not supporting that yet.

    Some other quickstart docs and hot takes from me on this hardware: https://blog.habets.se/2023/01/VisionFive-2-quickstart.html
