Summary :
SAP Note outlines the key strategies and technical settings required to optimize the performance of SAP transport processes, crucial for minimizing system downtime and maintaining efficient maintenance intervals. It suggests using at least NFS 4 when the transport directory is NFS-mounted on UNIX systems, deactivating opportunistic locks on Windows, and adopting an "import all" strategy when applicable. Details include setting "lock_check_wait_time=0" and leveraging parallel import processes. It also advises regular cleanup routines and upgrading to specific R3trans versions for different databases to handle imports more effectively. Further, employing system-specific log directories and selective language imports are recommended to boost performance.
