WoW:Lua object memory sizes: Difference between revisions

Upvalues that do not change only uses 4 bytes per closure. The below code will use 20000 + 4000 = 24000 bytes:

  local semistatic = "hi!"

  for t=1,1000

   x = function() print(semistatic) end

  end

However, upvalues that actually ''change'' use an additional 32 bytes. The below code will use 20000 + 4000 + 32000 = 56000 bytes:

   x = function() print(t) end

  end

And finally, a mix: The below code will use 20*2*500 + 4*2*500 + 32*500 = 40000 bytes

  for t=1,'''500'''

   for i=1,2

   end

  end
