Local writeback cache utilizes the SSD on the client PC to store cached data locally. This improves performance by reducing reliance on server resources for write operations.
- To activate local writeback, simply check the designated option in the client's edit settings.(Figure 1)
Figure 1
- To ensure this option functions properly, the writeback disk must be an SSD or NVMe, formatted with a 32K allocation unit size, and set up as a single partition. Failing to meet these requirements may cause client restarts or freezing issues.
- Enabling local writeback reduces the load on the server’s writeback disk.
- On the local writeback disk, you will see two files: C.CCachex and D.CCachex. The letter before .CCachex corresponds to the drive letter being cached for example, C for the system image and D for the game disk in this case.(Figure 2)

- If the file shows as 0 KB in Windows Explorer, that’s normal. You can view the correct file size by right-clicking the file and selecting Properties (Figure 3).

- CCBootClient uses the first disk detected on the client side for local writeback. If there are other disks present, remove them to avoid conflicts.
- Avoid using faulty or outdated SSDs or HDDs for writeback, as this may lead to performance issues.
