Performance dropping is more complex than the software blocking issue. You can use TMPerfTool.exe to find the high-loading running process and add it to the Behavior Monitoring Exception List or contact Trend Micro Technical Support for further assistance.

To begin identifying the issue, follow the steps below:

1. Contact Trend Micro Technical Support to obtain a copy of the TMPerfTool file.
2. Copy the TMPerfTool to the machine with the problematic agent.
3. Right-click TMPerfTool.exe and select Run as administrator.
4. Click Analyze. The Trend Micro Performance Tuning Tool will start to monitor the CPU usage and event loading.

   

   If a red highlighted row appears, it means that the Trend Micro Performance Tuning Tool found a system-intensive process. In the example below, the process is mspdbsrv.exe.

   

5. Select the highlighted row and then click the plus (+) button to add this process the exception list.

   

6. Verify the CPU usage. Do one of the following:
   • If the performance did not improve, click the Undo button to undo all the changes. Select another highlighted process.
   • If the performance improved, select the process and then click the minus (-) button. If the CPU usage increases again, then you have found the system-intensive application.
