Subject: [patch 0/4] net: percpufy frequently used vars on struct proto
Date: Tue, 7 Mar 2006 17:58:08 -0800	[thread overview]
Message-ID: <20060308015808.GA9062@localhost.localdomain> (raw)

Following patchset converts struct proto.memory_allocated to use batching
per-cpu counters, struct proto.sockets_allocated to use per-cpu counters and
changes the proto.inuse per-cpu variable to use alloc_percpu instead of the
NR_CPUS x cacheline size padding. 

We observed 5% improvement in apache bench requests per second with this 
patchset on a multi NIC 8 way IBM x460 box.

Can this go into -mm please?

Thanks,
Kiran
