Downlink Burst Allocation - 500000 vs 2500000

Our current deployment has Downlink Burst Allocation set to 500000 vs the maximum 2500000. Is there a benefit to a lower max downlink burst allocation? My simple understanding of burst is it allows the AP to transmit an allotment of data at maximum speed based on the modulation until it reaches that cap and returns to the sustained speed.

Is there a benefit to lower max downlink bursts?

On the AP-side, no - leave these at maximum. On the SM-side it makes a huge difference. Massive bursts means the SM will DL or UL at max air speed for a very long time before kicking back to a throttled rate. This is rife for abuse and can quickly overcome your other rate limiters like the Sustained Bit Rates, and cause fairness problems.

Our standard practice is to set a decent size burst and then drop down to a sustained rate that is lower than the advertised "up to" speed. So say on a 10 Mbps plan we burst the download for ~8 megabytes, then the sustained rate drops down to 9 or 8 Mbps. This increases web page load times over a plain 10 mbps rate limit (because the web pages load at maximum air rate or whatever I capped it at), but sustained traffic is a lower hit. This is good for everyone as BitTorrent, Steam, etc doesn't slam the AP as badly, but also dropping to a lower sustained rate quickly greatly improves streaming services as there's less buffering, less adaptation, less switching quality, etc.
