Slow performance following RHEL 6.2 to RHEL 6.5 upgrade

Solution Verified - Updated -


  • We upgraded one of our application servers to RHEL 6.5 from 6.2. Since then, we are seeing poor response times on some of the nodes.
  • We have been using some custom settings for hard disk; readahead and read_expire - prior to the upgrade this worked well.
  • With the 6.5 upgrade we also added tuned with a custom profile. Is it possible this is causing any sort of conflict?
