That's an extremely vague question. You need to explain what you are using your servers for, what performance issues you are worried about and so on. In general though, performance is only one of many concerns you need to think about when deciding which OS to use. Do the program you need exist? How stable and tested are they? Is cost your main motivator? If so, have you factored in time needed to learn a new platform? How important is community and paid support? -- Digimer Papers and Projects: https://alteeve.ca/w/ What if the cure for cancer is trapped in the mind of a person without access to education?
