Slow machine

I suspect the following quote from Xorg.0.log is not standard for X5000s but means something is wrong with my machine?

This system behavior affects all architectures, and it has been reported to XOrg as a bug, but they do not seem to think it is an issue. Regardless, it isn't anything to be concerned about.

Bug report response: "The messages are quite rate-limited now (see 5faa3b7a) so you should only get 5 per hour per device.
Those messages are (in part) a way to point out that libinput's behaviour, where it is affected, isn't actually libinput's fault. There are a few cases where a delay by a 10-20ms will significantly affect behaviour. Button debouncing and cursor jumps for example. And of course the threshold has to be something, so I'd rather have it at the shortest timeout that may cause adverse behaviour.
The reason we have that message is because we used to get a lot of libinput bugs filed for this problem when there was nothing we could actually do about it.
But if you don't notice any effects, you can simply ignore them."
