Hi Aray, We set:
- Idle Instances: 1 - Automatic - Pending Latency: Automatic - Automatic The primary setting to eliminate user latency is to set minimum idle instances (not automatic), so it warm ups at least one idle instance before users make requests. If you have large spikes in load, you may want to set it even higher than 1. But I usually don't have large spikes.
