CPU utilization internal maintenance

On the other hand, when the CPU utilization is high, but trade performance can not keep up, and the CPU is processing transactions inefficiently or is practiced are not directly related to transaction processing. CPU cycles are diverted to internal maintenance activities, such as memory management. You can easily delete the following actions:

• large queries at the right time to beat rush hour

• The independent application programs that could be better done on another computer

You can use the resource cpu utilization of the formula of the previous section to evaluate the response time of a CPU heavy. However, high CPU utilization does not always indicate a performance problem. The CPU performs all calculations necessary to process transactions. The more transaction-related calculations that performs a certain period of time, the greater the throughput of this period. As long as the commercial speed is high and seems to be proportional to CPU usage, high CPU utilization indicates that the computer is to use the maximum benefit.

When CPU utilization is high, a detailed analysis of the activities that the database server performs disclose all sources of inefficiency that can occur due to misconfiguration. For information on the analysis of server activity database

If the response time of transactions is increasing to such an extent that the delay should be acceptable, the processor can be overwhelmed, commercial cargo may be too high for the management of the computer. Slow response time may also indicate that the CPU is processing transactions inefficiently or CPU cycles that have been diverted.
