Hi there, I visited your site and it is relatively snappy. Categories are loading in 100ms and threads in 230. If the site is hosted in Romania (based on the .ro TLD) then that is to be expected because I’m over in the US.
If speed is still a concern for you, I would check to see the resource usage during things like pageload. 2 cores aren’t really a lot so if Redis is slamming your CPU it will slow things down but obviously at least for me things are fine at the moment on your site.
