AMD could probably make a killing by putting out old processors with

And I figured out where to put pti=off on my
various GRUB lines, so now
it boots with it off. And my desktop latency is back to 10msecs. :)
That is good to know. And depressing, one more thing to add to the
latency performance checklist. Set RT permissions, add user to audio
group, etc. ...oh, and one last thing, you need to decide whether you
want better performance or want to protect against malicious software
reading you kernel memory. You do have separate dedicated computers
for audio and banking, right? And a third for general web use? Just
make sure you banking and web browsing computers leave PTI enabled,
it's probably OK to disable it on your dedicated audio computer since
you don't connect it to the Internet.
