Looks like it’s a VM on AWS so I assume you have root access to the server. You should install something like New Relic which will tell you what the slow parts of your back-end application are (the things you need to fix).
From the outside it is a black box and it could be anything from server config to the application code on the server to external services that it calls out to.
