    Agreed about the assembler, but one way or the other, x86_64 is the only
    arch we support.

    Makes many nanoseconds of difference to us for our latency numbers. At
    the low latency numbers we measuring (1.29us), this is a very important
    difference to our customers.

    Good point. I'll ask around here why we're doing this.

    I'll see what I can do.
