The following patches change struct proto.memory_allocated,
proto.sockets_allocated to use per-cpu counters. This patchset also switches
the proto.inuse percpu varible to use alloc_percpu, instead of NR_CPUS *
cacheline size padding.
We saw 5 % improvement in apache bench requests per second with this
patchset, on a multi nic 8 way 3.3 GHZ IBM x460 Xeon server.
Patches follow.
Thanks,
Kiran
