Thank you in advance for taking time to reply to my question.
Processing power is mostly utilized by large agents, view indexing, and replication. If you are handling a lot of sessions, it can alleviate some issues. The main question is, what was CPU utilization before you got the processors? Domino is not capable of SMP, per se. It will use all 4 processors, but you cannot tell it to use CPU1 for Update, CPU2 for Replication, etc. If your CPU was constantly pegged before, this should help. If it wasn't before, then all four processors will just idle along happily. It is important to gather statistics before any hardware upgrade. You need to determine if your performance problems are CPU related, memory related, I/O related, or network related.
