PageSpeed: reduce initial server response time

Look: PageSpeed Test

Analyzing for the first time, TTFB is high.

In the second attempt, there is no TTFB error.

How to solve this?

Thank you help


- Shared hosting
- LiteSpeed license type: Standard
- Wordpress


when I delete everything from Google, the speed is much better.

Already did that. However, what I describe above (TTFB on the first high page load) continues.
