All my processes for open tabs seem to average 70-90% CPU (that is one core) for a full 25-post page now.

It seems to kind of be a combination of mistakes on the developer's end, and the browser's.

Developer:
  • He uses javascript to fade the opacity from 0 to 1, or 1 to 0 explicitly in the style.
  • He also puts some stupid script block before each rating list that defines a minimum opacity, instead of doing a more normal 'data-minimum-opacity' in the rating list's div.
  • When the opacity is 0, he doesn't set the 'visibility' CSS properties on his '.dark_postrating_inputlist' CSS class to 'hidden' or 'collapsed' so that all the buttons don't do a full render pass
Web Browser:
  • They don't take the obvious shortcut for opacity: 0 and treat it as being implicitly 'hidden' or 'collapsed'

setting visibility to hidden reduces the average CPU consumption to 10% for me from the average 70-90%.
What really seems to kill CPU is the great number of these ratings that are animated gifs; without this visibility:hidden, it seems to keep drawing them and animating them in the background.
And also to be fair to the developer, he had made a single spritesheet, and didn't expect people like DU to upload another 50 ratings without a spritesheet, and then have a larger number of animated ones too.

A little script for stylish to curb the worst of its excesses.

Code:
@namespace url(http://www.w3.org/1999/xhtml);

@-moz-document domain("www.rpgcodex.net") {
  
  /* curb the worst excesses of the ratings */
  ul.dark_postrating_inputlist[style*="opacity: 0;"] {
    visibility: hidden;
  }
}
