In KerioControl deployments, enabling or disabling the Generic Receive Offload (GRO) feature can significantly impact bandwidth performance. The ideal GRO configuration depends on the presence of Apple devices (macOS, iOS) in your environment.
Understanding the Impact of GRO
Generic Receive Offload (GRO) is a network option designed to increase bandwidth efficiency by aggregating multiple receive packets into a larger single packet. While this feature can lead to bandwidth improvements, its impact varies depending on the devices within your network.
- Environments with Apple devices: Enabling GRO in networks containing Apple devices may result in a noticeable decrease in speed.
- Environments without Apple devices: Conversely, environments without Apple devices can benefit from enabling GRO, experiencing increased bandwidth and smoother performance.
Configuring GRO in KerioControl
Adjusting the GRO setting is straightforward and can be done via the Local WebUI of KerioControl. Here’s how:
- Access the KerioControl Local WebUI.
- Navigate to Configuration -> Interfaces.
- Select the desired interface and click on Advanced.
- Here, you will find the option to enable or disable GRO based on your network environment.
FAQs
- Q: Can we have different GRO settings on different interfaces?
- A: Yes, GRO settings can be adjusted individually for each interface, allowing you to customize network performance based on the specific requirements or devices connected to each interface.
- Q: Which version are the GRO settings available in the WebUI from?
- A: GRO settings are available in the KerioControl WebUI starting from version 9.4.3 Patch 2 and later. Ensure your system is updated to this version or newer to access these settings.
By following these guidelines and adjusting the GRO setting accordingly, you can ensure maximum bandwidth utilization and overall network performance in your KerioControl deployment.
