[patch 0/4] net: percpufy frequently used vars on struct proto

From: Ravikiran G Thirumalai
Date: Tue Mar 07 2006 - 20:54:55 EST


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.

Thanks,
