My website has been on monitoring status and this is my report for 1 month. I haven't or modified any code. But there is some fluctuations. Is it odd or is it this normal? As I am on shared hosting, should I talk to my host about this??
That is normal. You are not going to see the same page load time for every page visit. Factors that effect page load time are optimization, network congestion, server issues. The only one you truly control is optimization.
