After months we upgrade two test board (rb532) to 3.0rc1 from 3.0b5.
The wireless transfer speed (on same placement, and same frequency) better than 3.0b5 (3MByte/s tcp ftp with 3.0b5 and 4.51MByte/s with 3.0rc1 in 802.11a turbo mode, but performance is terrible.
3.0b5(and 2.9.x) was really stable (but only 3.0MByte/s) the RC1 connection absolute not stable (3-4% packet loss in 1000 packet) somtimes, the connection stop 1-10 second and after everything is ok. Logs shows nothing.
This is known bug (or feature?/missing documentation?)
An overload of packages (new features) can overload the router memory and cause the CPU to max out.
When this happens, performance / stability is an issue…
This is only from what I have seen on my 532s…
The earler versions with the lesser memory amounts seem to be the issue…
Memory allocation and cpu utilization not problematic. The cpu or memory utilization or high transfer not cause of wireless stability in my test environment. I think rc1 wireless stack may more vulnerable in noisy or reflective environment than 3.0b5 (or 2.9).
