(e.g. create an account(Domain) on cPanel, then you will see it sync to the ADC in minutes.) It takes 5 minutes because the process pauses, giving the Apache configurations time to completely update before the changes are pushed. (We have found that the PkgAcct::​Restore account action took the longest time to update.)
