Tuning Guidelines

Follow certain principles when tuning system performance. These principles help pinpoint performance bottlenecks and tune system performance more efficiently.

These tuning principles include:

1. Comprehensive analysis of resource bottlenecks: Do not analyze issues only from a single perspective. For example, if the CPU usage is too high, the problem may not be caused by the CPU itself. Instead, the cause may be that the memory capacity is too small and the CPU is busy processing memory scheduling. Therefore, analyze all possible issues of the system to determine the real performance bottleneck.
2. Considering the impact of tools: When using performance analysis tools, note that these tools occupy certain system resources including CPUs and memory. Therefore, consider the impact of the tools to obtain the real system performance status.
3. Adjustment on a per parameter basis: During performance tuning, modify only one parameter at a time. If you modify more than one parameter at the same time, it is difficult to determine which parameter actually causes the performance change, which increases the tuning difficulty.
