[Need help to make this skript faster to load]

Hey guys! I ran into an issue while using script. I am currently using skript with the script-holo addon for making holograms and from what ive tested, a simple script like this one of about 35 lines takes up to 5 whole seconds loading (sometimes more). My problem is that I have many scripts of that type and the time adds up to 5-6 mins to load all. the problem is that my server wont let me in until all scripts aernt done loading but after 5 mins, the server shuts down (no players online for 5 min). so im basically stuck. I need help making it load faster.
