Disk Cache Settings
For IO-heavy applications like Primavera, set it to writeback.
- none: Provides the best balance of native-level performance and data safety by bypassing the host cache, making it the standard option for production and live migration.
- writeback: Offers the highest performance by using the host's RAM as a buffer, but risks a significant loss of data if the host crashes before syncing to disk.
- writethrough: Ensures maximum data integrity by confirming every write only after it hits physical storage, but suffers from extremely slow write speeds.
A reboot is required after changing this setting
