Measuring and Tuning Performance
Become familiar with business requirements, goals, and growth projections. Determine the user base and the transactions that will occur. Create usage profiles that reflect the actual page requests and operations that will take place after the site is operating at full capacity. Examine page size and reduce the use of graphics and placeholders to minimize latency for page turnaround. Consider your site’s bandwidth requirements. After you have a clear estimate of site usage, build a test bed that parallels the actual usage scenario(s). Use the MCMS TCA and the WAST to stress test your test site. Calculate the cost per user in CPU cycles and from that determine the hardware required to support the numbers of users you expect.
