This might be in the wrong forum / thread mekap04. But here's for starters. Do you have a lot of graphics? if so you should add this between your <head> tags to "preload" images. <script type="text/javascript"> <!-- Begin image0 = new Image(); image0.src = "http://www.site.com/path/to/image.gif"; image1 = new Image(); image1.src = "http://www.site.com/path/to/image2.gif"; image2 = new Image(); image2.src = "http://www.site.com/path/to/image3.gif"; // End --> </script> also, you should specify what blog program your using, hosting, and template?
certain themes are much more fast loading alot of the magazine themes seem to take a while to load due to the images i use a cache plugin for firefox which loads images on the whole site so they can be veiwed alot quicker
However, you should develop a site for everyone. Not everyone has the firefox plug-in ... Think of the end user and what they experience.
Based on my experience, one reason why a blog load longer is because of too much java script... I didn't say you cant put java script on your blog (coz adsense code is a java script!); just avoid putting too many java script. Add only those which is important.
javascript shouldn't slow down your blog that dramatically. Just use it correctly and you shouldn't have much problems. Sometimes if the javascript uses a connection to another site (like adsense), and the other site is loading slow, then it could effect yours.
