I understand your concern. Yes, I am using high end AP for throughput
test. I'd say 1.2 Gbps is not the worst case since we can achieve max
1.4Gbps according to our test. AFAIK, for most throughput cases, 1min
is
the minimum requirement. And I think, with more and more high end
products(even higher throughput) on the ways to the market, it is
highly
possible that 30s is not a safe time before overflow.
Well, 2 Gbps (goodput) would make it overflow every 16 seconds, so I'm
not sure where you take the 1 minute from :-) Maybe from 1.2Gbps PHY
rate.
But still, the only place we expose this is debugfs, so I'm not really
sure we want to spend that.
Note that I'm generally pushing back on statistics right now - I really
want to put some trace points or eBPF hooks in places that people can
use to keep their favourite statistics, instead of trying to cover each
and every use case in the stack itself.
Cool, great!looking forward to that change. :-)
