For about 10 day, my website loading very slowly, I am 100% sure that is not wrong with my server, because I run another website on same server, but another website loading under 1 second, but 2nd website that run flynax script, take between 3-6 second until loading, what happening with flynax?

Does the all users who running the flynax script has same files located on flynax server? I feel as like that, there is some files in flynax script located in flynax server, because that take so long time to loading.
