Performance & load testing

Find the limits before your users do.

Measure response times, throughput and failure behaviour using realistic workloads and data volumes.

Latency distributions and resource behaviour

Capacity decision

A bottleneck, an owner and a retest

An implementation example

A useful load test begins with a workload model

Reproduce the important mix of users, requests and background work. Observe queues, dependencies and resource limits, then distinguish a code bottleneck from a capacity or data problem.

Measure the workload you expect to serve

An application owner wants alerts that reflect customer impact.

A failure to account for

A healthy homepage masks failed background processing that users rely on.

Illustrative scenario, not a customer case study.

A fast average can hide a slow customer experience

The fragile approach

Send the same request as fast as possible

The result may bear little relation to production traffic or the slow path customers actually encounter.

The intended approach

Test representative demand and failure

Include realistic data, ramp-up, sustained load and dependency degradation alongside peak traffic.

Quality, security & governance

Reproduce demand before choosing capacity.

Workload modelling

Represent concurrency, request mix, data size and burst patterns from the expected use of the system.

Bottleneck diagnosis

Correlate response times with application, database and dependency behaviour under load.

Capacity decisions

Record the tested limits and the signals that should trigger scaling or further investigation.

Review the distribution, especially the slower requests, rather than the average alone. Tie the target to a user task and define what traffic and failures it includes.
