Being able to scan a website or web application quickly is certainly important, however, a fast scan isn’t always the desired outcome. There are cases where you might be scanning a web application on a web server with very limited resources (especially when scanning web applications on embedded devices), or perhaps you are scanning a web application with aggressive rate-limiting.
Whatever the reason, configuring a scan to run at a slower speed (throttling) is sometimes necessary. Acunetix makes throttling a scan simple.
To throttle a scan, navigate to the Target you wish to throttle, slide the Scan Speed slider in the Target Information page to suit your needs, then click the "Save" button.
The following are the values assigned to each setting on the Scan Speed slider.
1 Concurrent Request
Send requests every 120 milliseconds
2 Concurrent Requests
Send requests every 50 milliseconds
5 Concurrent Requests
Send requests every 20 milliseconds
10 Concurrent Requests
