  • YSlow. On the second tab of the performance test, you see your YSlow score. You shouldn’t be surprised that it’s different from the PageSpeed score because it is based on 19 different rules. Similarly to PageSpeed, YSlow gives you suggestions to optimize your website speed — for example, minify JavaScript and CSS, make fewer HTTP requests, avoid URL redirects, reduce cookier size, and so on.
