Limiter burst doesn't have any effect
No matter what you put in the burst field, the limiter behaves exactly the same as if it's 0 or null. Re-tested on the most recent 2.2 snapshot as of now, and it behaves the same in every 2.1.x stable release. For example the attached traffic graph, that's 4 Mb down (out), 2 Mb up (in) limiters. First run with no burst, second run with 400000 thrown in as the burst. Doesn't matter if that's a small number or huge number, it has no effect at all.
I'd be fine with just removing the burst field for 2.2 if fixing this is really involved.

dummynet burst on stock FreeBSD 10.1 does indeed work how I'd expect it to work. Ours doesn't have any impact whatsoever, with the exact same pipe config that has the expected behavior on 10.1. This has never worked, and there are too many 2.2 target issues already, so I just commented out the burst portion from the GUI bits. Can revisit later.

This issue is a blocker for me, I would really want the bursting functionality to work. I would like to help debug this issue as much as I can. I'm new to BSDs, but I'm quite experienced with Linux .. so I can hopefully get the hang of it
Can someone please guide me into how to debug this .. What commands to run, where to look .. I mean if the kernel level functionality is correct in FreeBSD 10.1, then this strikes me as just a configuration mistake (most likely) ? or a wrong command being run by the GUI ...etc
