作者简介：
Scott Barber is the CTO of PerfTestPlus (www.PerfTestPlus.com) and Co-Founder of the Workshop on
Performance and Reliability (WOPR –www.performance-workshop.org). Scott's particular specialties
are testing and analyzing performance for complex systems, developing customized testing
methodologies, testing embedded systems, testing biometric identification and security systems, group
facilitation and authoring instructional or educational materials. In recognition of his standing as a
thought leading performance tester, Scott was invited to be a monthly columnist for Software Test and
Performance Magazine in addition to his regular contributions to this and other top software testing
print and on-line publications, is regularly invited to participate in industry advancing professional
workshops and to present at a wide variety of software development and testing venues. His
presentations are well received by industry and academic conferences, college classes, local user
groups and individual corporations. Scott is active in his personal mission of improving the state of
performance testing across the industry by collaborating with other industry authors, thought leaders
and expert practitioners as well as volunteering his time to establish and grow industry organizations.
His tireless dedication to the advancement of software testing in general and specifically performance
testing is often referred to as a hobby in addition to a job due to the enjoyment he gains from his
efforts.
关于文章版本的补充说明：
这个系列的文章，作者是应邀于IBM的委托而编写的，这个版本可以在IBM的网站上找到。后来作者再次进行了一些调整并放到了perftestplus上，因此存在着两个不同的版本。如果你做过比较的话，你会发现相对于第一版而言，第二版做了不少的调整。我这里翻译的是perftestplus上第二个版本的。
关于“用户体验”的性能测试：
作者在各篇文章的介绍中，多次提到文章关注的是把外部用户的性能感受与客户满意度关联起来，关注两者之间的关系，也就是文章的中心“基于用户体验的性能测试”，因此在学习的时候，应牢记这个根本的出发点。
个人觉得，“基于用户体验的性能测试”和普遍意义上的性能测试从出发点上的差距，导致了在性能测试目的和方法上的关注的不同。通常的性能测试一般以能力评估、系统调优为目的，因此其更多的关注在并发、负载上，采用的性能测试方法也多为并发测试、压力测试、稳定性测试等，用固定的thinktime甚至忽略用户延迟来模拟高负载；而“基于用户体验”的性能测试，非常关注外部用户的对系统性能的真实感受，因为这影响到该系统的客户满意度，因此其侧重于使用各种方法/技巧实现对不同用户、不同使用情形的逼真的模拟，比如用各种分布算法来真正的模拟不同用户的不同延迟，以及各种可能的分支操作路径，这种测试的细致程度可见一斑。而这些，却通常被我们所忽略。
