You can use the bandwidth tester to test the capacity of a network connection. The bandwidth tester can help network administrators troubleshoot issues related to network connectivity. If a reviewer is experiencing network lags or is complaining about long wait times between documents, the problem might be due to issues related to insufficient bandwidth. In such circumstances you can use the bandwidth tester to detect and eliminate problems causing reduced performance on a particular machine.
The bandwidth tester allows you to execute latency tests, download tests, and upload tests in order to determine the cause of an underperforming computer on your network. A latency test reports the time in milliseconds it takes for a byte of data to reach its destination on the network. Download and upload tests allow you to specify a particular payload from 1 MB to 50 MB and get a report of the time it takes for that amount of data to be uploaded or downloaded on your network. These tests (if unusually slow on a particular machine) might reveal an issue with that computer's network card. If multiple machines are experiencing similar substandard behavior, then the issue is probably due to problems affecting the entire network.
Note: The bandwidth tester only provides the approximate throughput of the document viewer and isn't suitable for using to troubleshoot larger network issues.
See the following for details on the tests available with the bandwidth tester:
As a Relativity admin you’re familiar with the benchmark speeds in your environment. One of your litigation support specialists is complaining about network lags, and they’re not sure what to do. You decide to run the bandwidth tester from the viewer window to test latency, download, and upload speeds. After performing all three tests, you determine that latency is the issue because it took 10,000 milliseconds for a byte of information to reach its destination when it normally takes between 10 and 15. You suspect your network is experiencing unusually high traffic volumes, so you contact your IT department to perform network diagnostics.
Use the following steps to launch the bandwidth tester and execute various tests for network performance.
