Summary

You may encounter performance issues in the VDI environment while multiple virtual machines (VMs) are performing actions, such as on demand scan or pattern update.

Based on our testing, there was 20% reduction in VM capacity with OfficeScan installed. This means that if your hardware can deploy 100 VMs without any antivirus installed, it will reduce to 80 VMs once you install OfficeScan.

The following are the default settings in the VDI.ini file:

[TaskController]
Controller_00_MaxConcurrentGuests=1
Controller_01_MaxConcurrentGuests=3

We also tested this default setting on low-end environment and it also followed the 20% reduction in VM capacity.
If you have a powerful hardware and want the On-Demand Scan and Update to run more aggressively, then you can slowly increase the count and monitor the resource usage. This is because different environments may have different resource bound.

To modify the settings:

  1. Go to the OfficeScan server and open the Trend Micro\OfficeScan\PCCSRV\Private\vdi.ini file.

    Below is the default setting depending on OfficeScan version:

    For OfficeScan 10.5:

    [TaskController]
    Controller_00_MaxConcurrentGuests=1
    Controller_01_MaxConcurrentGuests=3

    Where:

    • Controller_00_MaxConcurrentGuests=1 is equal to the maximum number of clients that can perform scans concurrently.
    • Controller_01_MaxConcurrentGuests=3 is equal to the maximum number of clients that can perform updates concurrently.

    For OfficeScan 10.6 and above:

    [TaskController]
    Controller_02_MaxConcurrentGuests=1
    Controller_03_MaxConcurrentGuests=3

    Where:

    • Controller_02_MaxConcurrentGuests=1 is equal to the maximum number of clients that can perform scans concurrently.
    • Controller_03_MaxConcurrentGuests=3 is equal to the maximum number of clients that can perform updates concurrently.
  2. Slowly increase/decrease the count of each controller and monitor the CPU/Memory/Disk usage.
  3. Save and close the vdi.ini file after changing the value.
  4. Open the Windows Services console.
  5. Right-click the OfficeScan Master Service and then click Restart.
