Hello! I'm a big fan of your site (the skyrim version). I'm also a web developer that works a lot with site optimization. I noticed when visiting your site the first time at http://www.nexusmods.com/skyrim/, that it took a very long time to load (over 15 seconds) on my high speed connection. After investigating, I see that your site is including a GIGANTIC javascript file here:
http://www.nexusmods.com/contents/Scripts/BBoC-ebb38c0dc28aa966c8286fcc3abb19d6.jsThis file is over 900Kb and takes 12 seconds to download. That's going to bounce a significant number of new users. The first thing you can do is use a javascript minifier and turn on gzip compression, which gets get the file down to roughly 150kb. This simple change would dramatically reduce the time for the site to load for new users to your site. In addition, you are including the jquery library with your javascript. Instead, remove jQuery and JQuery UI from your javascript file and include it separately by linking to Google's hosted version i.e.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>And for JQuery UI:
<script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.9.2/jquery-ui.min.js"></script>Google's servers are significantly faster, the files can download in parallel with your other javascript file (which is now much smaller because it doesn't contain jquery), AND you save a lot on bandwidth. It's a huge win!
