These analysis mechanisms are quite sophisticated, though they have significant performance burdens and are not suited for consistent use in production environments.
尽管这些分析机制有明显的性能影响，并且不适合于在生产环境中使用，但是它们十分完善。

Although this is a sizing example, IBM sizing tools rely not only on the derived benchmark data, but also on analysisand feedback from both customer and internal production environments.
The cost is a combination of time and money for analysis, expensive downtime in production environments, stress, and a loss of confidence in the application and frameworks.
