Reduce initial server response time - NGINX - Varnish - Apache

When I check the page speed of my default page at https://hosting.siteurl.in/

i get good scores of 99/100

https://developers.google.com/speed/pagespeed/insights/?url=https%3A%2F%2Fhosting.siteurl.in%2F

But the initial server response time is 1s

When I build other sites on php, this is increasing and page speed score is falling.

Are there any ways to Reduce initial server response time.

make sure you are using php-fpm for more speed, also you can modify varnish nginx config for cache options you want/need

make sure you are using php-fpm for more speed, also you can modify varnish nginx config for cache options you want/need

I am using Apache-Varnish-NGINX

I  have enabled php-fpm

using php 7.4

Some times I have same problem
And other problem is the cache policy.
Any solution for that?

See my GtMetrix test: https://gtmetrix.com/reports/confraria.daniel-sousa.com/jX1wRrdM/

Reducing TTFB is critical to your visitors' page experience as it affects every resource referenced in your HTML, and directly influences how long it takes for your page to load. A slow TTFB may negatively affect your front-end resources as your visitors may only see a blank page while the browser is waiting for a response from the server.

If you want to be sure your site is up to standard, you can use GTmetrix.  It is a tool that allows you to analyze your web server response times, monitor your webpages, and test your speed on mobile. There are free and pro versions available. GTMetrix has both free and paid versions. Simply enter your URL, and you’ll see an overall score for page load time, which also includes SRT data.

Also, there are many other methods  to check your server’s speed and performance. Here are the top ones I recommend.

Use Reliable and Fast Web Hosting
Use a CDN
Optimize Databases
Performance Analysis.
Compressing Images.
Configure Caching
Minify Scripts
Minimize Redirects and Broken Links.
