Curious if anyone has worked on latency and jitter benchmarks in using
netlink, specifically with nl80211. Has anyone benchmarked this? Ben,
have you? If not for nl80211 perhaps this has been done before for
other netlink families?
You mean timing related to netlink configuration/report requests?
Yes.
No, I haven't bothered to do this... The way we use netlink is
mostly asynchronous..ie we just listen for events and process them
as they come in. Most of our configuration would be driven through 'iw',
'wpa_supplicant', 'ip', etc, and much of our stats gathering is through
the ethool get-stats API.
I would imagine any latency would be highly dependent on other applications
taking RTNL (for instance, creating/deleting lots of virtual stations,
mac-vlans, ip-address changes, etc).
Thanks,
Ben
