Code profiling should be done in the early stages of development, or as a first performance test after development.
代码分析应在开发的早期阶段进行，或将其作为开发后的第一个性能测试。
This can be invaluable for lower-level tasks such as code profiling or precise delays in device drivers and other time-critical code.
这对于某些底层任务来说是无价的，例如对代码进行分析，或者在设备驱动程序或其他严格时间要求的代码中进行精确的延时。
Before moving into full performance testing, consider using a code profiling tool to analyze the application for potential inefficiencies and bottlenecks.
进行全面性能测试之前，请考虑使用代码分析工具对应用程序进行分析，以发现潜在的效率低下问题和瓶颈问题。
