I looked at specific requests and the code being executed and most of them do not rely on any other external services. For most of the day today, latency did come down to <100ms. Then around 6pm PST, it started going up again. But I think, I might have a clue as to what might be going on...or atleast I hope. At about 5pm, I changed min_pending_latency from automatic to 440ms. I just changed it back to automatic, I'm hoping that will bring the latency back down.
Though, the change IMHO should not have made a difference because for most of the day before the change, I had 2-3 idle instances just sitting there doing nothing. I figured that I might be able to bring down the number of instances I am getting charged for by making the change... Let's see what happens with this experiment.
