As I've looked in the code abouts these things to present some patches,
there are different concepts :
- message levels as DEBUG, NOTICE, WARNING, ERROR...
- additional message fields as HINT, CONTEXT...
I think that this is not related to level or fields. so
"performance_hints" looks misleading to me. I would take a
"performance_advices" or "performance_checks" as these are not used yet,
and the levels may be notice/warning... and the hint field is not
necessarily used.
Well, this is just to talk;-)
