2.3.4 Scaling hardware versus performance tuning

Scaling hardware may be an easier solution from an implementation perspective than performance tuning, but it may not be easy to translate that into a business case for it.

Sometimes, however, the opposite is also true. Instead of a person spending months investigating how the performance of a well-tuned system can be improved further, it may be cheaper to add more hardware to your site.

Thus, you should consider the pros and cons of each approach.
