A peak season test starts from a load model built on your own order history, not from a generic user count. This post gives the template and a ramp plan.
Load model template
| Driver | Where the number comes from | Converts to |
|---|---|---|
| Orders per hour at peak | Last peak's busiest hour, times the planned growth | API calls per second on order intake |
| Pick lines per order | Order history, same period | Pick tasks per hour in the WMS |
| Scans per minute per device | Handheld logs or a timed floor observation | Requests per second from RF devices |
| Active devices | Shift plan for peak | Concurrent sessions |
| Carrier label calls | Parcels per hour | External API calls per second, with carrier limits |
| Tracking events | Parcels in transit times events per parcel | Inbound webhook or EDI 214 rate |
Ramp plan
- Baseline at an ordinary day's busiest hour, to confirm the model reproduces known response times.
- Step to forecast peak in equal steps, holding each step long enough to see queues settle.
- Hold at forecast peak for the length of a real peak shift.
- Push above forecast until a limit appears, and record which component hits it first.
- Repeat after fixes, using the same script and data, so results compare.
Open-source tools such as k6 (see the sources) can script these steps.
