http://www.machinimapalooza.com is my website. I tested my site on Google PageSpeed & I got a 81 out of 100, which isn't that good. Regardless of the PageSpeed, my site just feels slow. I run my site on http://www.nimbushosting.co.uk/ with a plan that has room for growth. I have 3 skins installed & 60 addons. I know that 60 addons is probably a lot, but not enough to slow it down that badly. Google PageSpeed says to "Improve Server Response Time" & "Leverage Browser Caching," but I really don't understand what they want me to do. Can anyone give me suggestions on what to do by just a quick overview of the site? Any help is great.
