First Byte Time (back-end processing): 0/100

With min load.

How to reduce it.
For starters, try testing instead of That will get rid of the wasted time from the redirect.

The remaining time issues are going to be application-specific on your back-end and it's hard to tell what it is doing from the outside. It is usually something like a lot of database queries or calls to external services but you need to instrument the back-end to know for sure.

I usually recommend something like New Relic but it's going to depend on the level of access you have to the server that the app is running on and if you have developers that can look into it.
