Full Version: First time byte problem
You're currently viewing a stripped down version of our content. View the full version with proper formatting.

I've been optimizing the index of this webpage to get the best performance but I'm unable to reduce the First time byte. Even I have 100 score in all the individual results, first time byte keeps going bad Dodgy

Here is the test if you want to take a look:

I appreciate any suggestions.

The first byte time is going to be something you have to look at on the back-end (we can't see what is causing it from the outside).

It can be anything from:
- Database performance issues (check your slow query log if you are using a database)
- External web service calls made by the server
- Overloaded server
- Server that has run out of available processes to handle requests
- and a bunch of other things

Is the application something you wrote or is it built on top of a platform?
