Revision 195ca3b122c02cf21ce64f211d9474600da80e80 authored by Rajkumar Manoharan on 15 March 2012, 17:35:28 UTC, committed by John W. Linville on 26 March 2012, 19:07:25 UTC
When we have downlink traffic alone and the station is going thru
bgscan, the client is out of operating channel for around 1000ms which
is too long. The mac80211 decides when to switch back to oper channel
based on tx queue, bad latency and listen time. As the station does not
have tx traffic, the bgscan can easily affect downlink throughput. By
reducing the listen time, it helps the associated AP to retain the
downstream rate.

Numa policy hit/miss statistics

/sys/devices/system/node/node*/numastat

All units are pages. Hugepages have separate counters.

numa_hit	A process wanted to allocate memory from this node,
		and succeeded.

numa_miss	A process wanted to allocate memory from another node,
		but ended up with memory from this node.

numa_foreign	A process wanted to allocate on this node,
		but ended up with memory from another one.

local_node	A process ran on this node and got memory from it.

other_node	A process ran on this node and got memory from another node.

interleave_hit 	Interleaving wanted to allocate from this node
		and succeeded.

For easier reading you can use the numastat utility from the numactl package
(http://oss.sgi.com/projects/libnuma/). Note that it only works
well right now on machines with a small number of CPUs.
