A recent question asks, "How do I find the cause for a huge difference in performance between two identical servers?"

This appears to be getting shot down as "Not a Real Question" and I'm somewhat confused as to why:

• The question describes a real problem that the asker is experiencing.
• A good, canonical answer to this question surely could be valuable to future visitors.
• The question asks for general strategies -- what to look for and how -- and is not requesting product recommendations.

Why would this not be a real and appropriate question?
