What happened?

i tried installing this awesome mod, and everything loads but 1 problem
it increases the packs load time to 5-6 mins while before it was around 2 mins
ive been using a good couple of hours deleting mods and looking at cpu usage while trying to figure out which mod was causing it and it seems like when dimensional doors is present the boot process becomes single cored looking at the numbers
it never gets above 50% and for the most it sits at around 15-20% and i have a 6 core CPU

this is my pack its pretty heavy problem why the problem is bigger and went by unoticed before
