It was on a cheap Bluehost account. These shared hosts usually don't receive a lot of traffic, and often went to sleep which takes 20 seconds to wake up. The system wasn't scalable at all and we had occasional days of high-traffic when it mattered that would cause the site to remain fully inaccessible. I'm measuring response times at the server, with no network latencies. My optimization process involved reducing TTFB at first and then complete full page generation in later steps.
