# Max Concurrency By default, tests run with maximum concurrency, up to the limit available on your plan. Higher concurrency leads to faster test runs, which is especially useful for large test suites or frequent executions. If needed, you can lower the concurrency to avoid overwhelming certain environments or services. You can set the Max Concurrency value in **Settings → Account → Runner**. This setting controls the default concurrency across your test runs. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.does.qa/configuration/max-concurrency.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
