What should I look for, I have my collectd module graphing /proc/*/stats 
out.  But by comparing the graphs from a test with 2.6.30-rc2 to the 
2.6.29-rc3 kernel there are huge differences between network and cpu.  
The 2.6.30-rc2 graphs with fscache and cachefilesd look identical to the 
2.6.29-rc3 without fscache and cachefilesd.

If you would like I might have time tomorrow to run the tests again and 
email you a pdf of the graphs.
