This seems to confirm the idea of something happening = over time in the kernel as opposed to some congestion or other = environmental factor. This evening, I=E2=80=99ll look at either = updating your bug report or opening a new one. > On Sep 13, 2017, at 3:08 AM, Russell Haley = wrote: >=20 > Need some sort of script to monitor performance of various things.=20 > Netstat > Load average >=20 > Dtrace would be good for looking into locks,mem consumption at = specific calls. Start looking at how long each syscall is taking? Agree. At least in my case, it=E2=80=99s something that isn=E2=80=99t a = problem initially and then builds up/falls over and becomes a problem. > Have you compared against a linux image on the same unit? I started to setup the full access point config with Linux for testing, = but just didn=E2=80=99t have the patience to deal with it. I=E2=80=99m = not sure that will reveal much given what I=E2=80=99ve found so far. Thoughts? Thanks, Chris=
