Traditional Web performance testingdoesnt cut it
Traditional testing is expensive. Cost of licenses, hardware, and training
Time-consuming to implement
Idiosyncrasies of the software are often difficult tomaster.
Traditional testing is not realistic.
Scope is limited to internal, clean-room testing.
Not focused on end-user point of view
Misses too many pieces in the Web applicationdelivery chain such as content delivery network(CDN), third-party components, geography, etc.
