Hello, how are you?
I analyzed your website, I translated a .srt file to test the difference in performance. I noticed that the free host processes [login to view URL] at 4.59s while the host at Hostinger processes at 120.72s. This slowness can be caused by several factors.
Usually hosts as Hostinger set limits I / O, memory and CPU, and it is likely that your script is exceeding the resource limit, which makes the process is paused, and causes great slow processing.
