Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.snyk.io/scan-fix-and-prevent/scan-with-snyk/snyk-api-web/start-scanning/overview-scan-management/scan-duration.md). # Scan duration The duration of a scan depends on several factors and is not easy to estimate beforehand. It depends on: * Number of pages of your site: Scanning involves a certain number of tests per page, so the more pages you have, the more time the scan takes. However, this is not linear, because the number of tests per page also depends on several factors. * Number of inputs (injection points) per page: The more injection points you have on a page, the more tests the scanner performs. An input is, for example, a form field. A page with a large form takes more time to scan. * Performance of the server that hosts your site: If your server is slow (for example, if it takes several seconds to load a page), scanning your site takes more time. If your server response time is fast, the scan speeds up. The scanner adjusts its velocity automatically based on your site response time. If the average response time increases, the scanner slows down. If the average response time is stable, the scanner increases the number of requests per second. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.snyk.io/scan-fix-and-prevent/scan-with-snyk/snyk-api-web/start-scanning/overview-scan-management/scan-duration.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. 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.
