I engaged with a Laravel AMP project which uses Laravel 5.6. The project is launched in the server (apache http server) and running (also running other 4 sites on the same server). The server has:
- Processor : Intel(R) Xeon(R) CPU E3-1220 v3 @ 3.10GHz
- Memory : 16226420 kB (16GB)
When I checked the page with Webpagetest, it shows F grade for First Byte Time.
How can I improve the performance of First Time Byte to grade "A"?
