Listed below, are the most frequently reported issues related to SAP system performance:
- Database performance. The DBACOCKPIT transaction, in which we can observe the use of database resources (such as e.g. cache use) constitutes the central point to identify performance issues. By analyzing data, we can improve system performance and reduce resources used. In some cases there is no need to improve performance, such as e.g. for background tasks, which are made at night, and the result is needed by the users in the morning.
- Program execution. Interpreting results from many transactions gathering statistical data or detailed SAP system logs, we can analyze the program duration, determine where the program takes the longest to execute and why, and therefore try to optimize its operation or rewrite the code so that it is more efficient.
- SAP system check. Operational system performance, use of resources – RAM memory, use of CPU processors, I/O statistics, as well as the statistics of calls for tables or SAP system buffers. A SQL inquiry written ineffectively can result in high use of the CPU or in a large number of I/O operations.
