Mesh isn't really the best technology. If you have 2 radio units (2GHz and 5GHz) then APs need to share the same frequency on the 5GHz band. This causes lots of problems and makes the hidden client problem worse. If you have 3 radio units then you end up with a second 5GHz band but all the APs still need to be on the same frequency on that second band. If someone did a regular AP install (wired) and put every AP on the same frequency then that would be considered a very bad install. But it is normal for mesh. So you can end up with a lot of retries and hence jitter and latency.
