    There are 128-processor IA64 systems which run recent 2.6 kernels out
    there; the per-processor counters, RCU and page-fault scalability work
    has been instrumental to the necessary scaling for decent resource
    usage on these.

    IIRC, there were some patches being developed to improve pagecache
    scalability lately too, but I guess it all depends on what kind of
    workload you have...
