What disadvantages are there to set the MTU to the maximum possible value in ALL network adapters on a network (including virtual switches vmware esx)?
Why do not the producers as a default?
I do not understand the way to use a network card to 1500 when it already support the value of 9000!

This is not a default because you would need equipment at every step in the chain to also support jumbo frames (MTUs over 1500).
Not every NIC or network switch or router or firewall supports such large MTUs natively.
