I mean that only the slow platform uses more than 64 budget, even I set the weight to 256. That is, for the fast platform, the actual used budget is always less than 64, even the weight is 256. > Do you have some actual data on how the device performs with budget > of 64 and 256? And maybe perf traces to show where the difference goes? I tested that slow embedded platform many years ago, so I don't remember the actual data. I think the difference is more than 400Mbps.
