Oops, this was an old version, the up2date ones also took care of "used"
field.
I guess its time for a sleep, sorry again.
[PATCH net-next V2] neigh: reorder struct neighbour fields
(refcnt) and (ha_lock, ha, used, dev, output, ops, primary_key) should
be placed on a separate cache lines.
refcnt can be often written, while other fields are mostly read.
This gave me good result on stress test :
before:
real 0m45.570s
user 0m15.525s
sys 9m56.669s
After:
real 0m41.841s
user 0m15.261s
sys 8m45.949s
