本文介绍了一种强大的工具——性能追踪，用于分析ABAP程序的运行时间。此工具由SAP开发，可以记录数据库访问（SQL语句）、远程功能调用（RFC）、队列操作及SAP缓冲区访问等操作。通过使用性能追踪，用户能够启动、停止并评估程序的性能，推荐激活SQL跟踪、队列跟踪、HTTP跟踪和RFC跟踪。

Runtime analysis of ABAP programs

Performance Trace is a powerful tool for analyzing the runtime of ABAP programs. It enables you to record a program runtime for the following operations: database access (that is, SQL user statements), RFC calls, enqueue operations, and accesses to SAP buffers. Performance Trace is a tool that was developed by SAP and is thus identical for all database systems, except in the fine details.

To navigate to the initial screen of Performance Trace, select SYSTEM • UTILITIES • P!!RFORMANCE TRACE or use Transaction ST05. In this view, you will find buttons to start, stop, and evaluate Performance Trace. You can also find checkboxes for selecting the trace modes SQL TRACE, ENQUEUE TRACE, RFC TRACE, HTTP TRACE (as of Basis version 7.10), and BuFFER TRACE. Only the field for the SQL trace is marked by default. For standard analysis of a program, we recommend that you activate the SQL
trace, Enqueue trace, HTTP trace, and RFC trace.
