HELIOS LanTest
HELIOS LanTest is a macOS network and file-service testing utility used to measure throughput, locking, and related server performance.
What is HELIOS LanTest?
HELIOS LanTest is a native Mac utility for testing and measuring file-service and network performance on macOS. It helps administrators, support teams, and developers evaluate AFP-compatible file servers and local storage by running practical throughput and file-operation tests. Common use cases include checking read and write speed, measuring file and record locking behavior, and troubleshooting bottlenecks on shared volumes. The app is also used to assess printing and spooling performance in HELIOS-based environments. For Mac users working with file servers, storage, or network infrastructure, it provides a focused way to benchmark real-world file system activity rather than only synthetic disk tests. HELIOS LanTest is published by HELIOS Software GmbH.
Key features
- Measure read and write throughput on local disks and network volumes
- Test file and record locking behavior on shared file-server volumes
- Benchmark typical file system operations such as creating, opening, and deleting files
- Evaluate server and network bottlenecks during maintenance or troubleshooting
- Check printing and spooling performance in supported workflows
- Run tests against AFP-compatible file servers and local storage

Safety overview
Status: Safe
This is a legitimate network testing tool. Its activity is expected to include creating, reading, writing, and deleting test files on volumes you choose, so use it only on disks or shares you intend to benchmark. Those actions are normal for its purpose, but running tests on production shares can temporarily add load or clutter a location with temporary test data. Close sensitive work and select the correct test volume before starting a benchmark.
Recommendation: Keep HELIOS LanTest if you use it to benchmark file servers, shared storage, or network performance on your Mac. If you do not use HELIOS server tools or no longer run network diagnostics, you can remove it without affecting macOS itself.
