Just a fyi,

If anyone is running a 3ware raid card, check out the 3ware 
knowledgebase for  Q10036, which is Performance/Optimization: How can 
3ware read performance be increased in Linux?

It's worth the read, especially after my file/print/home directory 
server took 10 hours last night to rsync 60GB from one partition on a 
RAID5 IDE array to another partition on the same array.

I just made the first recommended change for max and min readahead to my 
3ware 7500-8 card and saw noticeable results in memory, load, and irq 
changes with the webminstats package, already. And the system "feels" 
more responsive.
