All of these arguments are red herrings. As I indicated in my previous
post, the current deferred update timer setting reduces performance both
in a low-latency and a high-latency environment. The drop in
performance from using a 10 ms DUT was much the same whenever I
artificially simulated 200 m

When the deferred update timer behavior was recently overhauled such
that it pushes out updates whenever the timer is triggered rather than
waiting for an update request from the client, the default DUT value was
also changed to 10 ms (from 1 ms.) Unfortunately, setting the DUT to 10
ms results in
