Tuning Process

To tune performance, you need to identify problems, find performance bottlenecks, and determine a tuning method based on the bottleneck level. Figure 1 describes the tuning process flow.

The tuning analysis flow is as follows:

• Server: Analyze the server performance from the hardware and software. Focus on the hardware indicators, including the CPU, NIC, hard drive, and BIOS configuration. Pay special attention to software tuning, including the application software and OS. The tuning of these indicators can greatly improve the performance.
• For network problems, you need to focus on the network bandwidth and network interruption. You need to check whether the core for handling network interruption is fully loaded.
• Client: Check whether the client performance meets the test requirements, especially for the HTTP short connections.
