BApp details: Request Timer
This extension captures response times for requests made by all Burp tools. It could be useful in uncovering potential timing attacks.
Results can be filtered by tool (Proxy, Scanner, Intruder Repeater), by target scope, and by matching a string in the URL.
Requires Java 8.
You can install BApps directly within Burp, via the BApp Store feature in the Burp Extender tool. You can also download them from here, for offline installation into Burp.
Please note that extensions are written by third party users of Burp, and PortSwigger Web Security makes no warranty about their quality or usefulness for any particular purpose.
