DB VMs and vSwitch Standard port group

hello
Fast question.
I have a DB VM (database) and 3 APPs (applications) that connect to the DB VM over the network.
is it better to put all 4 VMs in the same port group of a vSwitch Standard? Or on the contrary, is it better to separate the BBDD VM into a different port group than the other 3 with different vmnics (physical adapters)?

In other words, does VMware detect that the network traffic of the 3 APPs that go to the DB is in the same group of ports and does not go out through the physical vmnics and the traffic stays in the vSwitch?


Thank you

Traffic between VMs connected to the same port group running on the same host doesn't need to leave the host network adapter.

As soon as the VMs are spread across more than one host, obviously the traffic must pass physically.
