Has anybody played around with changing the Linux I/O scheduler when using ASM 
(11gR2) ?  I am wondering if any performance differences are to be found in 
using CFQ vs. Deadline vs other options, especially in a large RAC / SAN 
environment.  Right now we are using CFQ, and in my previous experiments on 
filesystems I did not get any noticeable difference in changing to deadline.
