With 2010 going to be more important for having a website that loads fast, i was wondering what you guys think of tools such as YSlow! everytime i run it, it throws up similar issues, and then when i implement them such as gzip compression it still shows as an error. Annoying. Also, some of the changes such as altering the order for my css and js files to be read, i can't do cause it will alter the site too much as some files have interdependecies. Is it best just to switch to faster hosting? Your comments/suggestions appreciated.
