Reason for the SAP R/3 System Running Slow


Check if there are long running jobs in the background during the peak times (SM50) or if users are running long running

transactions/big lists.

System performance cannot improve if Dia and Bck workprocess increased. In fact those itself will bring down the performance of the system.

* Do not allocate more the 2 bck process in peak hours
* Check if your hardWARE is adequately sized for these many users.
* Check for any jobs consuming more than 60% of you resource.
( STO6-DETAIL ANALYSIS-TOP CPU)


* Check if there is any NETWORK COLLISION AT SERVER AND USER END.
* Rate of ARCHIEVE LOG SWITCH OVER .
* All USERS use SAME SERVER AT A TIME
* Even USER with ALL SUPER USER AUTHORISATIION can bring DOWN SYSTEM PERFORMANCE AT TIMES
* TRANSPORTS, providing AUTHORISATION and EXECUTING RESOURCE CONSUMING REPORTS TO BE AVOIDED at PRIME TIME.
