In its simplest form, the growth of the system can be associated with the number of users in the system, both distinct users and sessions. If you have collected this data over a long period of time, it can be correlated and used, in conjunction with CPU and I/O performance counters, for your growth calculations. Using user count as a performance metric is demonstrated in Figure 6-10. By keeping track of the user count on a daily basis, you can see trends in the activity on the system. This chart was created by sampling the database using a select from sysprocesses and counting the number of users. This data was inserted into a database. After a few months, the data was very useful.

By having both CPU utilization and user counts as performance metrics, you can calculate the average and maximum CPU utilization per user. The CPU count is gathered from sysprocesses, and the CPU utilization is gathered from @@CPU_BUSY. With this value you can extrapolate the CPU utilization with additional users as shown hereL:

Planning for Future Growth
Planning for future growth should start early and be addressed on a regular basis. Long-term performance monitoring should be done and the results of this monitoring should be analyzed on a monthly basis. In addition, you should conduct regular discussions with your customers in order to plan for additional users and changes in the application. Keep in mind that changes to applications are not always improvements. A significant number of performance tuning activities are initiated by the need to tune a new version

of an application that does not perform as well as the current version. This is a very common problem. This is somewhat solved by using load-testing application revisions, but the majority of applications are put into production with no load testing.
Benchmarking and Load Testing
One way to help plan your system and to validate changes to your system is done via benchmarking and load testing. Benchmarking and load testing are similar in nature and just slightly different in usage. A benchmark is a performance test used to compare the performance of different hardware or software. A benchmark can be an industry standard test or a custom test used to measure a particular configuration or program. There are many companies that publicly publish benchmarks results. These results can be used to compare systems and are usually used by the publishing companies as marketing material. There are several organizations that are used to develop and facilitate standardized benchmarks. One of the best known of these is the TPC (Transaction Processing Performance Council; www.tpc.org). The TPC was founded in 1988. Its mission is to create standards and regulate the publication of database benchmarks. Microsoft is an active and leading member of the TPC.
Real World
TPC Experience
Three of the co-authors of this book Edward Whalen, Marci Garcia, and Burzin Patel worked as SQL Server benchmarking engineers at one time in their careers. Edward Whalen chaired the TPC-C subcommittee for several years, and all three have been involved in publishing record-breaking TPC results on SQL Server in the past. A load test is the practice of modeling the characteristics of a program or system by simulating a number of users accessing that system or program. When used to test a system operating at more than normal usage to the point of maximum capacity, it is called a stress test. There is really not much difference between a load test and a benchmark. Typically, a benchmark is used to compare various products, whereas a load test is used to characterize a single product. In either case, load testing and benchmarking can be used to characterize the performance of your system and to determine how future activity will affect your performance. In addition, by load testing your application each time changes are made to it, potential performance problems can be found before the application is introduced to the user community.
