All mail shares the same network connection, it shares the same
Postfix queue manager, it shares the same Postfix mail queue and
it shares the same file system, memory and CPUs. If you saturate
any of those things, there that will affect the delivery performance
of all other mail.
This is just like road traffic. If the road to the airport is
congested, then it does not matter if some vehicles have high
priority and others have low priority. All vehicles will be slowed
down.
