HPA Settler

Pre-performance-testing baseline calculator for resource requests/limits and HPA settings

Performance testing is always recommended before moving any recommendation to production. These numbers are a starting point for testing, not a production-ready setting.

What do you want to calculate?

Resource sizing HPA scaling Both

Current state

Current replica count

Deployment name

Resource sizing

Avg idle CPU usage

Avg idle memory usage

CPU load multiplier (idle to request) 1.3x

Memory load multiplier (idle to request) 1.5x

CPU limit ratio (request to limit)

Memory limit ratio (request to limit)

Baseline replicas (optional)

Maximum replicas (optional)

Leave both blank to size each pod independently from idle usage. Fill in either (or both) to size pods so the total expected load still fits within that replica ceiling: fewer replicas means each pod is sized bigger.

HPA scaling
