Note that my server does NOT have a RAID hard drive.

Correct behavior syncing to disk is not a bug. It's unclear what is the point of this report?

The point of this report is that an out of the box CentOS 6X installation executes MySQL 70 times slower than CentOS 5X. I am coming to realize this is probably not a deficiency of MySQL, but of CentOS (and other distributors), and apologize for the false alarm. I do believe, however, that MySQL should better document this potential behavior.

Hi, thanks for your report. However, this is something probably best reported to CentOS so that it can be addressed at the source of the issue.
