I notice that it took some time to load Flarum which I installed on a VPS (1GB ram). So I checked how many seconds does it takes to load and here is the output. And now Flarum official forum in other hand, just needs around 2 seconds to load it. Am I doing something wrong?

Edit: Memory usage and vswap usage is around 40% in the vps after I installed Flarum.
