Chris is quite right. These kinds of percent values can be very misleading.
However, You might want to check if cpu is used wisely
- is plsql_code_type native, which can make pl/sql execute with less cpu cycles.
- is Your algorithm and datastructures correct. Same things can be achieved with less work or with great effort.
You should find out how much time one execution takes and it is acceptable.
