Something interesitng:
I have 8 dell 2650's (dual xeon 2.8ghz+hyperthreading) and i've setup
the one machine above with the patches.. All 8 machines are incoming
MX/smtp machines which handle quite large loads (5gigs of mail per day).

machine 1: 
(mounted:noatime,nodiratime,data=ordered,alloc=skip_busy:dirid_groups,packing_groups)

  21:16:17  up 12:17,  1 user,  load average: 0.45, 1.04, 1.07
375 processes: 374 sleeping, 1 running, 0 zombie, 0 stopped
CPU states:  cpu    user    nice  system    irq  softirq  iowait    idle
            total    7.2%    0.0%   32.4%   0.0%     0.8%    5.2%  353.2%
            cpu00    1.8%    0.0%   10.6%   0.1%     0.9%    1.3%   85.0%
            cpu01    1.5%    0.0%    7.4%   0.0%     0.1%    0.9%   89.9%
            cpu02    1.7%    0.0%    7.0%   0.0%     0.1%    1.7%   89.3%
            cpu03    1.8%    0.0%    7.4%   0.0%     0.1%    1.5%   88.9%

Iowait total stays hovering at around the 6->8% mark..

machine 2->8: (mounted: noatime,nodiratime)

  21:14:31  up 1 day,  8:41,  1 user,  load average: 0.43, 0.72, 0.66
392 processes: 391 sleeping, 1 running, 0 zombie, 0 stopped
CPU states:  cpu    user    nice  system    irq  softirq  iowait    idle
            total    8.0%    0.0%   35.2%   0.0%     1.6%    0.8%  352.8%
            cpu00    2.0%    0.0%   11.1%   0.1%     1.5%    0.3%   84.6%
            cpu01    2.0%    0.0%    7.7%   0.0%     0.3%    0.1%   89.5%
            cpu02    2.2%    0.0%    7.7%   0.0%     0.0%    0.3%   89.5%
            cpu03    1.8%    0.0%    8.7%   0.0%     0.0%    0.0%   89.3%

The majority of the rest of the machines iowait hover around the 1%
mark.. CPU time tends to be about the same, just the iowait is much
much higher..
