Sampling should be performed after each step in the treatment process and from each point of use.
应在处理过程中的每个步骤之后以及每个用点处进行取样。
Sampling is the process of taking values from an input at regular intervals. The more values we take the more accurate the resultant representation.
采样是指每隔一定间隔从输入端提取数值的过程。取值越多，表现效果越精确。
The profiler can be used to attach to or detach from a running process to make sampling and gathering performance data easier.
探查器可用于附加到正在运行的进程，或从正在运行的进程分离，从而简化性能数据的采样和收集。
