I'd like to emphasize this point. 3.7 has some _very_ significant performance
improvements for database workloads; you will _need_ to run at least a 3.7
kernel to have an acceptable run speed for that type of workload (at least
in my experience). Seriously.
Also, the nodatacow option Hugo mentioned will also help.
Regards,
Wade
