My website Speed is good in Germany, the UK, the USA, and speed is less than 2 seconds.

I have to operate the site just in Australia and its speed in Australia is 9 seconds. As a beginner, I cannot figure it out how to correct it. I have used wp rocket but couldn’t sort out in Australia. Any suggestions will be appreciated!

Keep in mind that Cloudflare only caches static files (Images, CSS, JS) and all other files have to be retrieved from the origin server.

In which country is your web server? Judging from the following test, it’s in either western Europe or eastern US.
