How to Reset Buffers in Sap ?

Hi Friends,
Some-time its needed to reset some buffers in SAP For performance issues So here iam sharing the differnt buffer cleanup T-codes.
But Keep n mind Resetting of the buffers could change the performance of the entire system
/$DYNP - reset the screen buffer of the application server
/$SYNC - resets the buffers of the application server
/$CUA - resets the CUA buffer of the application server
/$TAB - resets the TABLE buffers of the application server
/$NAM - the nametab buffer of the application server
