How often is it recommended to conduct system testing under high load?

It is recommended to regularly perform system testing under high load, especially in the following cases:

• Before releasing a new version or major update.
• After significant changes in architecture or infrastructure.
• When planning scaling or load changes.

The frequency may vary depending on the project, but typically:

• For active projects — at least once every few weeks or before each major release.
• For less dynamic systems — once a quarter or as needed.

Regular load testing helps identify bottlenecks, prevent failures, and ensure stability under real load.
