Performance & load testing

Choose the workload.
Understand the bottleneck.

We help configure performance checks for browsers, APIs, and application services. Define realistic workloads, prepare a controlled test environment, and turn the results into questions your team can act on.

Targets, load, access, and run windows are agreed before testing
Different layers, different measures

Keep browser speed
and service capacity in view.

A browser journey measures the experience of a page. A protocol-level load test measures how a service responds to a workload. Scope both when your release question needs both.

01 /

Browser performance checks

Review loading and interaction behavior for agreed journeys, browser targets, and network conditions. Configure the chosen runner to keep measurements and supporting page evidence tied to the build.

  • Page and journey-level timing
  • Browser and connection conditions
  • Comparison with an agreed baseline
02 /

API and service load

Prepare or adapt load scripts with tools such as JMeter or Gatling. Define request mix, test data, concurrent users, ramp-up, run duration, and the environment under test.

  • Realistic workload composition
  • Response-time percentiles and throughput
  • Error rates and endpoint behavior
03 /

Baseline and regression review

Compare runs under documented conditions. Investigate changes alongside application and infrastructure context, then repeat the same workload to assess a proposed fix.

  • Versioned test plans and data
  • Comparable run conditions
  • Retest evidence and remaining questions
Plan before you generate load

Make the result
worth interpreting.

Capacity, access paths, test-data behavior, and background activity can change a result. Our consultants help prepare a run plan and the measurements needed to interpret it.

01

Define the question

Agree the critical transactions, expected workload, performance targets, and the decisions the results should inform.

02

Prepare scripts and access

Review the plan, data, dependencies, and direct network path. Confirm the environment and permitted run window.

03

Execute controlled runs

Start with a baseline, increase the workload as agreed, and collect service metrics and test-run evidence.

04

Interpret and compare

Review percentiles, throughput, errors, and bottlenecks. Retest changes under comparable conditions.

Evidence & handoff

A report with
the workload attached.

The agreed handoff should explain what was exercised, under which conditions, and what remains uncertain. Avoid reducing a run to a single average response time.

  • 01
    Workload specification

    Request or user mix, concurrency, ramp-up, duration, data assumptions, and load-generator configuration.

  • 02
    Measurement context

    Build and environment, response-time distribution, throughput, errors, and relevant resource or application observations.

  • 03
    Findings and next checks

    Endpoints or journeys to investigate, comparison with the baseline, limits of the run, and recommended retests.

An API before a busier release.

Model the important read and write journeys with safe test data, run an agreed workload, and inspect a slow endpoint alongside resource metrics. Repeat the plan after a targeted change.

Input
API definitions, workload assumptions, permitted targets, and measurable objectives.
Review
Response-time percentiles, error patterns, throughput, and environment context.
Handoff
A versioned run plan, results, and a focused list of investigations.
A few useful answers

Before you get started.

Confirm the coverage, tools, and access your team needs when we scope the work.

Can you use our existing load-test scripts?

We begin by reviewing your scripts, tool versions, dependencies, data, and reporting needs. The engagement defines adaptation and execution work for the chosen environment.

How do we choose a realistic workload?

Start with known user journeys, traffic patterns, and expected growth. Agree the mix, concurrency or arrival rate, ramp-up, duration, and test-data behavior before running the plan.

Can we test a private service?

Private-target testing requires an agreed network and access plan. The path between load generators and the target affects measurements, so we review it with your team as part of the run setup.

Does a passing test guarantee production performance?

Results describe the tested workload and environment. We document those conditions, compare against the agreed targets, and identify additional tests needed for a release decision.

Start with the performance question.

Share the journeys, expected workload, current scripts, and the release decision you need to support.
