    You can collect a ST12 trace for this transaction code and found the slowest part for further analysis. Also add a KBA for your reference: 2436955 - Step by step instructions on how to use ST12 trace for analysis.

    With SAT, you can find which subroutine(s) are the slowest ones. If these are standard routines, then raise a ticket at SAP support.
