First time byte problem


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?
