Num of instances

I have a question concerning performance that is related to the number of oracle instances that are running on a platform. For example, I have 5 applications (systems) such as accounting, manufacturing, etc that have been implemented in oracle. Each application is comprised of at least 30 tables. The total database is over 5 gigabytes. The machine is a sequent running unix and has 8 CPUs. We are thinking of switching to 5 databases with 5 oracle instances (each application has its own instance/database/CPU). Since oracle is architected to run on a machine with multi- processors, this should increase performance. Has anyone actually done this? What were the problems that were encountered? What are some advantages and disadvantages of this technique. Thank you for your time.
