I've had a website for a while and I'm using the free Cloudflare CDN. My host is a fairly cheap shared one.
I noticed that my website feels a bit slow when it is first loaded. I ran a Google Pagespeed Insights test and received a red flag for Server Response Time, which was 1 second. It consistently scores around the second mark, although every now and then it gets <0.3 seconds.
Does Cloudflare even help with this metric? How can I reduce the server response time on the cheap?
