Last updated on Dec 22, 2025 The Network Connectivity test can be used to locate network issues and bottlenecks. The tool sends test data to all Agents connected to the Coordinator, which in turn sends back the same data. Network performance for each Agent is recorded, with the test repeated four times to rule out random results. The Network Connectivity test can be started from the Agent Settings > Network > General page. Once the test is completed, the test results are displayed: The following columns are shown for each Agent tested:

Working with the Results of the Network Connectivity Test

Once the test is completed, check for any Agents marked as “Poor” in the Performance column. If such Agents appear, consider the following:
  • Check their machine’s hardware for outdated network cards which may need replacement.
  • Examine these machines’ network configurations for any differences from machines rated “Good” or “Excellent”.
  • Disabling these Agents permanently may have a positive effect on the build performance. The disabled Agent will still be able to run distributed builds, but will not be included in builds initiated by other machines. To keep the “Disabled” state between system reboots, use the Agent Settings dialog box -> Agent->Preferencespage.
