It seems like it is not a lot of overhead if any at all. Also the hardware design easily accommodates it. So why not if the work is already done?

    There is still some overhead. Enough that if you are doing HPC and running on your own hardware you might want want to disable it.

    I've disabled it on epycs for this reason but never touched it on ryzens.
