Right now my site hosted on a dedicated server CPU:- 8 core 3.3Ghz , 16gb RAM.
However, once I reach 1k+ user online the CPU gets full. Which means site start slow loading.
The site has Wp super cache installed, and for cdn I am using keycdn which is great. Also I am using only few necessary plugin. Now I am looking for a server which can take at least 2k + user without any problem, Please advice. Thanks
