For most home users there will be not much of a difference, probably, but I'm not sure. The older method reading the files was slow, because each exec'ed process had to reread the entire passwd and group files anew. With small files this was probably sufficiently fast. The new method will not have to read any files, though. It reads all infos from the local SAM, and it cashes the user and primary group data right fron the start. If i may hazard a guess, it should be slightly faster for most people. For AD users the answer is probably an "it depends". A slow network might be a problem. But one advantage always is: No more reading /etc/passwd and /etc/group files in each exec'ed process.
