    I don't know if it makes any difference to your findings, but
    I would point out the test hardware is neither representative
    of most devices supported by OpenWRT, nor those on the amazon
    best-seller list that I see looking from Germany:

    Five of the top-10 devices on that list are arm64 (little-endian,
    hardware TLB walker, typically 512MB of RAM), the others are
    mips32 (typically only 128MB, mostly single-core) and only
    the oldest one (Archer C7) of them is big-endian. I would not
    expect endianness to make any difference, but the 16x smaller
    memory of typical mips devices (ath79, mt76) might.
