About this series
Writing code for an application is only the first phase of the lengthy process required to deliver a robust product quality program. The code must be tested to verify its operation and accuracy. It is also often necessary to analyze the code to eliminate performance bottlenecks and resource waste (especially memory). Code must also be monitored to locate faults, identify usage patterns, look for opportunities for f
Analysis principles:• Specific Problem Analysis (this is due to different application systems, different testing purposes, and different performance concerns)• Locate bottlenecks in the following order, from easy to difficult.Server hardware bottleneck-> network bottleneck (for LAN, you can ignore it)-> Server Operating System Bottleneck (parameter configuration)-> middleware bottleneck (parameter configuration, database, web server, etc) -> applicati
