At times, after a client boots up, there might be a sustained high Write Speed on CCBoot (e.g., exceeding "1000M") even after 1:40 minutes. This results in performance slowdown for clients. Here are steps (refer to Figure 1) to address this concern.

Figure 1


1. Activate Superclient on CCBoot Server

   Enable superclient mode for a chosen PC (e.g., VM).

2. Perform Diskless Boot for VM

   Initiate a diskless boot for the specified PC.

3. Access Windows Task Manager

   Launch the "Windows Task Manager" after the client boots up.

4. Navigate to the Performance Tab

   Click the "Resource Monitor" button within the "Performance" tab (see Figure 2).

Figure 2


5. Identify High Write Speed Process

   Inside "Resource Monitor," choose the "Disk" tab and sort by "write." Identify the process causing high write-back speed using its "PID" value (e.g., "system" with PID 4) (see Figure 3).

Figure 3

6. Locate the Process

   In our scenario, the system writes a substantial amount of data on the write-back disk.(In most cases, the issue is related to Windows updates)

7. Uninstall the Problematic Program

   Remove the identified program causing the high write-back speed and shut down the computer.

8. Disable Superclient and Save Image

   After shutting down the client, disable the superclient mode and save the system image.

9. Resolve Write Issue

    This action will halt excessive writes on the server, eradicating lag or performance issues for clients.

10.If encountering issues with
Windows updates, follow the solution below.

a. Enable superclient mode and allow the system to complete Windows updates. Once done, save these updates.

b. Alternatively, access superuser mode and completely halt the Windows update process."
