In the following scenario:
- same hardware
- same mysql version
- same configuration settings
- same load
- using latest stable version of the OS
Does the OS has an impact on MySQL overall performance? The customer's IT staff is advising on chaning Ubuntu LTS with CentOS to improve performance.
Am I missing something?
I would undestand the impact of a distro like Gentoo or Arch Linux, but not really CentOS.
