Not that I'm aware of out the box. There are multiple good practices to follow. YSlow and Google Pagespeed are both great indicators of what you're doing wrong.

Not that I'm aware of out the box. There are multiple good practices to follow. YSlow and Google Pagespeed are both great indicators of what you're doing wrong. What you need to remember is that you should only 'load' what you need. Don't load a 1920x1200 size image if you're only displaying it as 240x150. Combine your stylesheets, create sprite images, load only javascript you need - try to stay away from flash and similar embedded objects. Make sure your files are served compressed (except images) and that proper caching is in place. You can't always blame the technology.
