This article describes a known issue that can negatively impact restore speeds when users restore files via the Code42 app or when administrators initiate a device restore from the administration console. Following the steps below to increase the TCP/IP buffer size may help greatly improve restore speeds in your Code42 environment.
On-premises Code42 environments where the Send and Receive buffer sizes in Settings > Device Backup > Network > Advanced TCP/IP are too low. The most common low value is 64 KB, but anything other than the OS Default could negatively impact restore speeds.
There are two reasons the buffer sizes can be too low:
- Prior to Code42 server version 3.6.3 (released in early 2014), the default buffer sizes were automatically set to 64 KB. If you used a Code42 server version older than 3.6.3 and have continued upgrading to newer versions, the old default settings may still be in use.
- In the administration console, an administrator manually changed the buffer sizes to a value that is too small.
To increase the TCP/IP buffer sizes and improve restore speeds:
- Sign in to the administration console.
- Select Settings > Device Backup.
- Select Network.
- Go to the Advanced TCP/IP section.
- Select OS Default for both the Send and Receive buffer size.
Selecting a value other than OS Default is recommended for experienced network administrators only. Incorrectly configuring these settings can adversely affect network performance and impact Code42 app connectivity.
- Click the push icon for both settings.
- Click Save.
- On each user device, restart the Code42 service, or restart the entire device.
