I'm running my site on AWS Lightsail Wordpress 4 GB RAM，2 vCPU，80 GB SSD instance. I've activated a caching plugin on Wordpress "WPRocket" to optimize JS, CSS and also use CDN for images. The problem is when testing with webspeed platform such as Pingdom, the initial server response time is so long.
There's wait time 2900ms for every page.
I've run commend to test TTFB. The result is as follow
1 Connect: 0.000614 TTFB: 0.629312 Total time: 0.629377
2 Connect: 0.000449 TTFB: 0.587795 Total time: 0.587838
3 Connect: 0.000500 TTFB: 0.528136 Total time: 0.528178
4 Connect: 0.000458 TTFB: 0.546313 Total time: 0.546354
5 Connect: 0.000449 TTFB: 0.526605 Total time: 0.526645
I'm not sure if I have to do something more on server side to optimize further.
