Alrighty, having read through the other responses I'm inclined to agree
something's not playing nice with certain hardware:

Oops, somehow missed those follow-ups. Thanks, I'll catch up.
Have you tried booting one of the newer kernel versions from power-off?
I'll be sure to give that a go, thanks.

Just an update: I am still encountering similar performance issues with the
4.9.0-1 kernel that was recently promoted to testing. In fact, the 4.9.0-1
kernel may be the worst yet in terms of this specific issue, with IntelliJ
starting so slowly as to be effectively unusable. One time the entire

Tried 4.8.0-1 with similar results. Perhaps slightly better, but not much.

Dear Maintainer,
Experienced poor system-wide performance since linux-image-amd64 pulled
down 4.7.0-1. Tried to investigate what was going on, only to discover that
tools like top/htop were unable to report per-process
