A performance hint from the dev window, not the compiler. An OnUpdate
script ran in nearly every frame while its frame showed nothing: the frame
has no size or is fully transparent, as a frame made only to run code usually
is. OnUpdate runs once per rendered frame, 60 to 240 times a second, for as
long as the frame is shown, so a script that only waits or polls costs time
in every frame.
When the work is needed every few tenths of a second, use every or
repeating from wowlua:timer instead, which run on C_Timer and cost
nothing in between. When the script only matters while some UI is open, set
it in that UI's OnShow and clear it with SetScript("OnUpdate", nil) in
OnHide, or hide the frame that carries it.
