: Compatible with the LST Server for more accurate "RAM-to-RAM" testing without hard drive bottlenecks.
If you are using Cisco, HP Aruba, or Netgear Pro switches with "PH" firmware, the tool is sometimes bundled inside the switch management CD. Check your hardware vendor's "Utilities" section.
Although LAN Speed Test v3.5.0 uses RAM on the local machine to avoid local drive bottlenecks, the target device still writes the data to its disk unless you are running a dedicated virtual server setup. If your target NAS relies on old, slow mechanical hard drives in a non-RAID configuration, the write speed may top out around 80-100 MB/sec regardless of your network capacity. Conclusion
To measure the actual data transfer rate (throughput) between two nodes on a local area network, identifying bottlenecks such as cable faults, switch limitations, NIC driver issues, or file-sharing protocol overhead.
: The file stream stays entirely within the RAM pools of both machines. This isolates your switches, routers, and ethernet cables, exposing the precise maximum threshold of your physical local infrastructure. Navigating the "V350PH Link" and Download Paths
: Version 3.x is often sought after because it was one of the last "fully portable" versions before the software transitioned to newer licensing models in version 4.0+. ✨ Key Features of v3.5.0
: Click the "Start Test" button. The software will write the file to the destination (upload) and then read it back (download).
The interface features a single-screen layout with a clear "Start Test" button. How LAN Speed Test Works
