Performance & scalability testing

Moving from one-off load tests to a structured performance practice aligned with business SLAs and peak events.

Load & stress SLOs / SLAs Peak readiness

Strategy & objectives

Start with business expectations, not just tool configuration.

  • Defined performance objectives with product and engineering: what fast enough means and where.
  • Identified critical flows and components (search, checkout, APIs) to focus effort instead of testing “everything”.
  • Agreed on metrics (latency, throughput, error rate) and SLOs that mattered to both tech and business stakeholders.

Scenarios, tooling & environment

Practical performance testing that fits into real release cycles.

  • Designed load, stress and soak scenarios based on historical traffic patterns and expected growth.
  • Used suitable tooling (e.g. Locust / JMeter / k6 ) depending on stacks and team skills.
  • Worked with DevOps to provision realistic, isolated environments for regular performance runs where possible.

Integration into release process

Making performance checks a habit, not an afterthought.

  • Scheduled regular performance runs ahead of big campaigns or feature launches with clear pass/fail criteria.
  • Shared reports focused on decision-making: “can we launch?”, not just graphs of response times.
  • Created feedback loops so findings informed architecture, caching and scaling decisions.

Impact & reuse

A pattern for making performance part of normal quality.

  • Improved stability during peak events and reduced surprises like timeouts or cascading failures.
  • Teams had a clearer picture of how close they were to limits, enabling smarter scaling and cost decisions.
  • The same model (objectives → scenarios → runs → decisions) can be applied to any new product line.
