I just saw the screenshots posted above, which makes me think I'm wrong. It looks more like the red bar is the time taken (and charged), but the blue bar is the time the app spent blocked waiting for the return. Eg. your script waited for 5 seconds for the response, but for some reason (transmission time? blocking?) it was only 1 second of CPU in the datastore. Hopefully someone knowledgeable might know for sure :-)--
