Proposed change

  • Predetermine how to run the handler instead of every time (don't call asyncio.iscoroutinefunction every time) -- This is effectively the same thing we do in HassJob to eliminate this call every time since it does an expensive inspect under the hood.
  • Make hass a closure variable to avoid the lookup each time
  • Offload the bytes/text conversions to aiohttp since it already handles it

Almost every request has to go through here, which means almost any improvement here will speed up every request.
