Is like a year or more when i started to have a problem with loading arts, videos and such but i never really investigated to it until now because it was tolerable, but now i am hopeless. I have a 100 mb/s up and down optic internet and have no problem with streaming or watching 4k60 or even more in real time, but here i am struggling with FHD image of 5mb size art that is loading sometime more that 10 seconds and watching any kind of video is simply imposible except 480p even 720p isnt loading enough without jagging, and native art´s 1080p or even 1440p+ is like 10 second waiting for 1 second of watching. Its really frustrating so i would like to ask if there is some solution for it or something more complicated. Thank you for all answers and help ^v^

I loaded an 11.8 MB image in about 5 seconds on a suboptimal connection. I don't think e621 is the problem.

You could try downloading the videos. Save the video directly to disk, instead of opening the Download link in the browser which will just stream it in a tab.

You could select 850px image width in Settings to get smaller images.

You could load 480p video samples.
