I don't know exactly the parameters gmetrix uses to measure the speed, but I'm pretty sure they profile everything until the last resource has loaded. When your browser stops showing you the loading bar/the content has been rendered, there can still be scripts and images loading in the background.GTMetrix doesn't really give you the speed at which people load your website. Generally divide that by 1.5 or 2. For example, GTMetrix says my website loads in 3.60 but even with caching cleared, it takes me 2.70 or less to load it. The size of your page is also big, try to reduce it to 1MB or less.

GZip compression is already enabled, otherwise it would be shown as error in top of Gmetrix. The website is fine, the problem is how the plugins are made / what they've done.Use gzip to compress your site by over 80%... That's half of the job done.
Then minify your CSS and java script. This should solve your problem.
Try W3 Total cache plugin and remove any other plugin you are using to speed up your site. Plus look like something is wrong with your server too.
Trying W3 total cache will help.
https://www.wpbeginner.com/plugins/how-to-install-and-setup-w3-total-cache-for-beginners/What options should be toggled to "on" within the W3 Total Cache plugin?
Should the "Minify" option be enabled?
Should browser, CDN, object, and fragment cache all be enabled?
I just installed it on one of my sites yesterday.
