AppEngine Standard in us-central1 is having a significantly longer warump P90-tile latency than what it has in other regions (e.g. asia-northeast1).

According to the customer's test, the difference could be 9.6s (us-central1) vs 3.8s (asia-northeast1).

This difference seems to be irrelevant to the complexity of warmup handler, because even with a hello-world warmup handler, the difference would be 2.5s (us-central1) vs 1.5s (asia-northeast1).
