radv: slow GPL (fast) link times
Investigating this a bit today with zink + Tomb Raider and I found wildly different link times, some of which were not what I would call "fast".
Many links were around 2.2-2.3ms (very slow imo), and there's quite a few that were longer: I saw several that took ~7ms and even a few that took 10-15ms. This is not really acceptable from a perf perspective since it still guarantees stuttering, and I think we need to really get deep into this and improve perf by a factor of 10x (at a minimum) for the functionality to be usable as intended.
