How are the server times, Ajax times and Network Times calculated
I am using the Ajax Dynatrace product and I was curious about how certain metrics are calculated.
1) Server time
For a particular page ( say example.com/login) Do you add up all the 'Time to First Byte ' for all resources on the page ? and/or subtract the DNS time,connection time,transfertime , network time etc to arrive to server time OR a different way ?
2) Ajax time ?
Since the response comes back in chunks , what event / marker specifies the start and end of Ajax times ?
Are they included in the Total Page load time ?
3) Network time
How is this calculated ?
4) Dynamic request time
How is this calculated ?
Hi
Check out the links in the following forum post: Best Practices on Web Performance Optimization
There you find the exact definition of all these timings
