I haven't been idle after the year, I have been optimal. Because the CPU time of the Server who found the database was found to be 0, this is too horrible.
So first check the code of the DAO, see if there is no connection to release, optimize SQL. Next, an optimization database, increase the number of connected numbers, and increase the federated index of the table. Finally, the optimization system, increase the number of open files, and more. I think there is still a case where the CPU idle time is 0, I am afraid I have to try Oracle.
