Summary

In this chapter we began our progressive case study of a fictional e-Commerce web site. We demonstrated some of the calculations for network capacity estimates. We also took an initial pass at HTTP session memory requirements based on information from the customer. After generating these estimates, it's time to talk over the initial findings with the customer. As with all estimates, they're only useful if they match reality on the production web site.

The next part of the book focuses on actually running a performance test against a web site, obtaining useful results, and making appropriate tuning adjustments. We begin in the next chapter by discussing the test process. Also, we continue this case study in Chapters 14 and 15 after we further develop some more testing concepts.
