Can I get 100 web vitals without cache plugins?

GreenShift has conditional loading of all assets so there is a big chance that you will get a 100 score without any caching. But it would be best if you had good hosting with a small TTFB and pay attention to your content. We don’t recommend using heavy media on the first screen of the site. Also, replace all image files to webp or SVG format and avoid using external scripts and heavy plugins
