3.5 ms is between 5x - 53x worse than what you'd see out of gigabit ethernet, depending on the quality of the equipment, but even at the low end this is absolutely something noticeable in any application heavy on round-trips (such as those mentioned). Nothing breaks my focus more quickly than an unpredictably slow or janky UI, it is far from a made up scenario, just open an explorer window pointing at an SMB share with a few hundred JPEGs with uncached thumbnails and you've already hit it. I'd much prefer consistency of a slower network than usability that evaporates at random, else what is the point of preferring a wired network over wireless in the first place?
FWIW, listing a directory or opening a single file over SMB is at least 4 round-trips, that's 14 ms burned on lag just for a single thumbnail, in the best case, and it only multiplies from there.
