I've had at least three very severe slowdowns in the last 10 days. Nothing usable really, had to leave the Mac alone for 3-5 minutes before it became usable again.
In two cases when using Parallels, in another case just browsing with Safari. No external screens connected.
Don't have a theory yet, the CPU did not seem to be the problem.
Will investigate further if it happens again. Thing is, I don't like to open Parallels at all but if it triggers the problem I'll have to.
