The appliance that supports DNS Cache Acceleration is configured by default to serve up to 1,000 concurrent clients that serve recursive queries. To improve query performance for the appliance, Infoblox recommends that you increase this setting to 40,000 concurrent clients.

1. From the **Data** **Management** tab, select the **DNS** tab and click the **Members** tab -> *member* check box -> Edit icon.
2. In the *Member* *DNS* *Properties* editor, click **Toggle** **Advanced** **Mode**.
3. When the additional tabs appear, click the **Advanced** subtab of the **Queries** tab.
4. Select the **Limit** **number** **of** **recursive** **clients** **to** option and enter the value **40000**.
5. Save the configuration.
6. Click **Restart** if it appears at the top of the screen.
