Average generation time would be useful, for example to be able to segment only traffic with very slow load times.
This could help for many use cases such as: identify whether problems are limited to a few particular slow Page URLs, or idenfity whether users from some particular countries have more performance issues, etc.
Thanks much @mattab. This is exactly what I was searching for. Has this been incorporated in the product? Please let me know if this was done.
I feel this is a very important feature if not already done, as this is going to help identify/troubleshoot some of the performance concerns from the end-users.
