[Bug]: Extremely slow performance

[bkutasi]

What happened?

On almost all pages, the load times are extremely long, the most time is spent on js/image loading and handling.

The page on DreamshaperXL loaded so slowly that lighthouse even gave up.
Here are some reports where you can view the details/blockers:

I see two immediate improvements that could be made: use webp images with lower quality to save on traffic(the quality will be virtually the same on the small previews). The other is to consider not loading images on model pages unless the user scrolls down (or even place a button the "load images"), and only show a couple of modes during model search (~10-15).

The other problems are harder: the js eval time is very high for chunks/framework-19fa3454641a47fe.js. Somehow the size needs to be smaller and more efficient. Removing features depending on your stack could help.

Steps to reproduce the problem

Load any page on civitai.com.

What should have happened?

Less image loads, more optimized js would speed up page loading and enhance user experience.

I am having similar issues. front page seems to load fine with no lag, I can also navigate to a model page and it is somewhat OK, but as a soon as I click on an image, from either the front page or from a model page, to view the image and it parameters, everything just slows to a crawl and takes forever to load or scroll.

I get the same results from my desktop, Surface and work laptop. Using Chrome, Brave or Edge browsers makes no difference.

I found a similar complaint on reddit : https://old.reddit.com/r/StableDiffusion/comments/1awjm4k/whats_up_with_one_civitai_tab_being_in_focus/

There are some comments but nothing too concrete. There was a comment about adblock+reload loop before, but it seems to be gone now. I tested the site with and without adblock and the performance was roughly the same, so I don't see an issue with that.

I get the same experience for images as you the site self combusts, but adding to thatI cant load the page without hiccups. The images and the all the js takes a very long time to load and if i scroll during load or do anything at all everything is choppy. The only quick load experience i get if i disable javascript.

I have about a hundred tabs open simultaneously, and the site cannot load at all at this point. Edge just suggests the tabs are hung and should be killed.
