The latter.

Robocopy reads a file into a local buffer and then writes that buffer to another file. (Of course, it only reads and writes part of a larger file and repeats in a loop until finished.) If a file is accessed on another host via UNC then the file access uses the network.

To optimize the network flow you need to run robocopy on one of the servers involved.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
