I have a managed stack of Netgear GS752TPS switches that are joined together into a single stack using fibre.

I also have - for example - a terminal server with four NICs using teaming. I also have other servers etc but using this as an example, should I spread the connections between the switches 1, 2, 3, and 4 or is the difference negligible from putting all four into switch 1?

The patch panel connections are spread between the four.
