How to understand the process generated by transaction.duration.us?

Why is the transaction.duration.us time different from the time seen on chrome devtools?

Hi @wajika,

Can you give more details on which field you are comparing the transaction with the one on chrome devtools?

We use performance.now for measuring Transaction and span timings which is used by almost all timing API's like Resource Timing, Navigation Timing etc.

Thanks,
