I implemented W3 Total Cache and JQuery Image Lazy Loader (which Bobby wrote about here -> https://www.40tech.com/2010/10/15/improve-wordpress-site-performance-and-look-cool-by-loading-images-on-demand/) at the time when I switched over to my new theme.

Not only does the site appear to load more quicky, but the numbers back it up. I used the latency tracker plugin, and my load times have dropped dramtically – almost every request is taking just a second or so. I’m not even using the advanced features – I just activated the plug-in and clicked a few buttons.

The exception to this is when someone delves into the older pages (going to /page/36/, for example). These requests can sometimes take 12-30 seconds (but at other times are much quicker). My first thought is that this is somehwo related to the way the database in indexed – placing more emphasis on newer data? Let me know if you have thoughts.
