I have tried the option you suggested. It does not seem to make a difference in loading time. It does make a difference in size.
However, you are right about the fact that it should be faster. On two other workstations, the nag screen shows within 2 seconds.
I don’t see what could be delaying the loading process that much, but I will search a bit harder on my workstation.
If I find the cause I will share it here.
