How browser agent determine Server and Network time?
Hi,
We have an application where we used browser agent to analyze client side performance. We didn’t instrument any server components of the application.
In the browser performance report we saw values for Network and Server time. We were expecting only network time because we only had browser agent and it cannot determine the server time from the total round trip time.
Now that we have network and server time the question is how is the browser agent determining the server time and network time?

Hi Sreerag
Here is a description of most of the metrics that our browser agent calculates - its a bit old but still valid: Best Practices on Web Site Performance Optimization
Server Time is basically the "time to first byte". It is of course not 100% accurate as it includes some network time as well - but it basically tells us how long it took the server to start responding the first bytes after the request was sent by the browser.
if you move the mouse over the column header you should also get a short description of each meausre

Thanks Andi, we also thought it could be first byte time.
These best practices articles are really helpful.
