It's way slower than without the commit, but only temporarily then it recovers.

In case you have etqw, I am testing @1920x1080 fullscreen with everything
turned on/up as high as possible.

I've found another issue, but it's not related to this or llvm and could be
quite old as I've not left etqw running for ~30 mins for some months.

The issue is I run out of mem (4 gig). I'll open a new bug when I've had more
time to test with older kernels.
