I suspected network issues between LPAR2 db server and net-backup server, but the full backup of LPAR2 which runs on the weekend completes in the same time as LPAR1. This specific performance issue is only noticed for RMAN incremental backup. I also verified, it's the same RMAN script runs on LPAR1 & LPAR2, and the RMAN logs are having same contents on both sides. Pasting below the topas output taken while the incremental backup running.

Thanks
