Intel Nodes Only
Orka 2.0 introduces Apple ARM-based nodes support where the IO is boosted by default. Therefore, the option
--io-boostis applicable only to VMs deployed on Intel nodes. Read more about Apple ARM-based Support (Beta) to see which commands and options are supported for VMs deployed on Apple ARM-based nodes.
When creating a VM configuration, you can choose to disable the IO Boost option. All VMs deployed from this template will run on settings aimed at improving their IO performance.
Keep in mind that, based on your workload, the observable performance boost might vary. For IO-intensive workloads (e.g., multiple or frequent read-write operations), you will notice a significant improvement. For non-IO-intensive workloads, the change might not be noticeable.
You will not experience any performance degradation.
Before you begin, make sure that your Orka environment is updated to Orka 1.5.0 or later.
Quick command summary
orka vm create-config [--io-boost yes/no]
orka vm create [--io-boost yes/no]
By default, IO Boost is enabled on the environment level. To disable it for a particular VM configuration, you need to explicitly set the option when creating the configuration.
For VM configurations created with Orka 1.4.3 and earlier, this setting is disabled.
To prepare for the update and to take advantage of the IO performance improvements, consider updating your existing VM configurations.
- IO Boost is applicable only to Mojave 10.14.5 or later. For earlier macOS versions, make sure that IO Boost is disabled to avoid issues. See Defaults.
- You can disable IO Boost only in direct mode for the Orka CLI, OR via the Orka API.
Once you create a VM configuration the IO Boost option cannot be changed. To do so, you need to re-create the VM configuration and explicitly specify the IO Boost during the creation.
Create VM Configuration or VM with IO Boost enabled.
To explicitly disable IO Boost, set the
--io-boost option to
no in the Orka CLI, or
io-boost: false in the Orka API.
