The Server Timing tab in browser debug tools is an useful feature for implementors of Activate aiming to optimize server performance. This tab provides detailed insights into various server-side performance metrics, helping you understand the time taken for different stages of server processing and response delivery. Key metrics include:

- DNS Lookup Time: Duration to resolve the domain name.
- Connection Time: Time required to establish a connection to the server.
- SSL Handshake Time: Time taken to complete the SSL handshake.
- Time to First Byte (TTFB): Time until the server sends the first byte of the response.
- Content Download Time: Time taken to download the response content.

By analyzing these metrics, implementors can identify bottlenecks and make informed decisions to enhance server performance. 



# Using Server Timing insights in Activate

Requires Activate 8.2.7+

Server timing insights are enabled by default for members of the Activate Developers role who can view Server Timing insights from the timing tab of a request in standard browser debug tools. To disable Server Timing insights set //Resources/Configuration/Web/IsTelemetryEnabled to "False" (this parameter doesn't exist out of the box so may be need to be created with a type of string or boolean)

The database call that resulted from the request and the time it took is displayed. Hover over the insight to get the full detail.
