you have installed the WP fastest cache plugin.
now I have 2 other deactivated plugins( I think they are for speed of website and optimization as well)
This plugin will link your WordPress application with all the performance optimizations provided by SiteGround
W3 Total Cache:
The highest rated and most complete WordPress performance plugin. Dramatically improve the speed and user experience of your site. Add browser, page, object and database caching as well as minify and content delivery network (CDN) to WordPress.
Please let me know should I activate them to have a better speed or they conflict the WP fastest cache? and I should remove them
