That's basically what I've been trying to make clear all along: people
should keep an open mind, watch what happens, and not make any
assumptions. There's no clear cut preference for one scheduler or the
other in all situations. I've seen CFQ do much better, you and Albe
report situations where the opposite is true. I was just happy to see
another report of someone running into the same sort of issue I've been
seeing, because I didn't have very much data to offer about why the
standard advice of "always use deadline for a database app" might not
apply to everyone.
