The performance varies for me. List-pages (like https://e621.net/post/index?page=n) and post-pages (like https://e621.net/post/show/id) vary from 3 to 10 seconds to load the page. The time the images take to load is not included. (Btw: how are these pages called?)
I didn't log in multiple times, but the one time I did was subjectively faster than usual. Profile-pages also load faster than I remember them to do.
Images and thumbnails load as fast as always. I assume they are stored on a different server?
Edit: Submitting this post was also faster than it used to be.
Also I'm in Austria here.
