Configuring Disk Cache Settings

For I/O-heavy applications like Primavera, go with the writeback setting.

• none: Strikes an excellent balance between native-level speed and data safety by skipping the host cache, making it the standard pick for production and live migrations.
• writeback: Delivers the highest performance by using the host's RAM as a buffer, but you risk substantial data loss if the host crashes before information is saved to disk.
• writethrough: Guarantees maximum data integrity by confirming each write only after it reaches physical storage, though write speeds become very sluggish.

A reboot is needed after you modify this setting.
