Just wanted to follow up on this: Idle instances set to 1: 7 of 10 requests were loading requests (20-30 seconds) Idle instances set to 2: 3 of 9 requests were loading requests (and cost was about 4 times as much)
This is a test app, with no other traffic, no new versions uploaded, etc., and these requests were about once a day for the last few weeks. I'm giving up on finding a setting that will mimic always on for low traffic apps, and just setting up a cron job to ping the apps regularly.
