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.
