Increase TMCM's resource for processing requests to improve GUI performance. To resolve the issue:

1. Stop the TMCM and Trend Micro Infrastructure (TMI) services.
2. Back up the systemconfiguration.xml and processmanager.xml.
3. Go to cmd.exe, then go to C:\Program Files\Trend Micro\Control Manager.
4. Execute the following:

   XMLModify.exe m_iLimitSaveFileTempLog 10 SystemConfiguration.xml
   XMLModify.exe m_iLogRetrieveThreadNum 30 SystemConfiguration.xml
   XMLModify.exe m_iCommandTrackingLogPurgeRange 30 SystemConfiguration.xml
   XMLModify.exe m_iLogRetrieveBatchTaskNum 5400 SystemConfiguration.xml
   XMLModify.exe m_iPurgeAllTimeoutCommand 1 SystemConfiguration.xml
   XMLModify.exe m_iCommandThreadNumber 15 SystemConfiguration.xml
   XMLModify.exe m_iCommandTrackingTimeOutMinute 30 SystemConfiguration.xml

5. Open the ProcessManager.xml in the Control Manager folder.
6. Change the "-thread_number" from "20" to "50":

   <Process Order="1" ID="ID_CMD_PROCESSOR" Filename="CmdProcessor.exe" CommandLine="-component_name=SC_TVCS_Command_Processor -thread_number=50 -scheduler_thread_number=5 -mrf_thread_number=1 -timeout=120 -enable_debug=false -db_conn_pool_size=30" WaitingTime="0" Priority="HIGH_PRIORITY_CLASS"/>

7. Change the "-iocp_thread_number" from "11" to "25":

   <Process Order="6" ID="SLF_PRODUCT_TVCS" Filename="MsgReceiver.exe" CommandLine="-act_as_sc=false -component_name=SLF_PRODUCT_TVCS -thread_number=50 -timeout=240 -enable_debug=false -db_conn_pool_size=20 -iocp_thread_number=25" WaitingTime="0" Priority="NORMAL_PRIORITY_CLASS" />

8. Restart the TMCM and TMI services.

If the issue persists, collect and send the Case Diagnostic Tool (CDT) logs to Trend Micro Technical Support.
