Precise performance bottleneck locating

1. The performance bottleneck is defined as the most important factor affecting performance at a certain time point. The performance bottleneck has only one condition at a certain time point;

2. All performance bottlenecks can be attributed to the issue of program code;

3. Performance bottlenecks are divided into three types: System Bottleneck path bottlenecks and trigger bottlenecks;

4. You can use the system-level bottleneck tool to locate the specific operation, function application, and code-level analysis tools to locate the function.
