I need to do performance tuning of my demo system as its response time is very slow.In performance tuning I am little bit aware of its basic concept like how to find that which response time is low and how to recover that but issue is that we daily stop our this server in the evening and start it in the morning so due to it I can not follow that concept of finding which response time is slow as due to buffer refresh daily obviously its database time will be high.
Now I want to check that whether all parameters like buffer are set correctly to provide us a good response time.
One more thing I want to confirm My RAM is 4 GB initially I was using 12 GB paging memory now i am thinking it to change it to 16 GB,Will it effect my system performance and how can i make it effective in my SAP system.
There is no such kind of rule of thumb exists for SAP buffers.
Fot tuning those SAP buffer parameters, please refer to my first reply.
