hello Sadiq,

Entries in red means there is lots of buffering which means the size of buffers is too small and hence this is slowing down the performance

best method is Increase the value of these buffers by RZ10 profile parameters by around 15-20%

refer to http://help.sap.com/saphelp_nw04/helpdata/EN/c4/3a6ecc505211d189550000e829fbbd/content.htm

Hi

Performance tuning is a detailed analysis task in which u have to check every aspect of the system, like which reports u r facing in slowing down the performace. Especially the Z reports (Customized). u can check the system processes by using SM51 and analysis the programs. If u r having issues with custom reports then it is recommended to make them tuned by ABAPER.

For Buffer analysis in ST02, u should review Extended Memory used level, and then tune buffers accordingly. But Recommendation is to read Note 88416 (Zero Memory Management)

Focus on these Parameters:

rsdb/ntab/ftabsize

rsdb/ntab/entrycount

rsdb/ntab/irbdsize

abap/buffersize

*Also keep in mind there is no general rule to set parameters, it totally depends on ur system analysis.
