LST Server is an add-on available at http://www.totusoft.com.
Do I need LST Server to use LAN Speed Test?
Using LAN Speed Test without the additional LST Server, writes the test file to another computer's hard drive. Network tests will be limited to drive speeds, caches, etc. This can be the performance test that you want to see as most of the time you are writing files to other hard drives (file servers, etc.).
Using LAN Speed Test with LST Server writes the test file to the server's memory and takes the hard drive out of the picture. This will give your network's true performance. LST Server can be installed on any computer in your network (it is not limited to just a server). Testing to LST Server also gives you control over which network interface to test with.
How do I use LST Server with LAN Speed Test?
First, run LST Server on the computer that you wish to test your computer (Client) with. Next, on the Client, run LAN Speed Test (this program), make sure that 'Testing to LAN Speed Test Server' is checked, type in the ip address or computer name of the server in LST Server IP' (the server's ip address is shown under 'Server Status' in the LST Server program), and make sure that the correct Network Interface is selected. Now when you run the test, the file is being sent to (and read from) the LST Server's memory instead of another computer's hard drive. This takes the slowest device of the network out of the picture for more 'True' network speed accuracy! In my tests using LST Server, I am seeing network speeds of 800 - 900 Mbps on my 1000 Mbps network compared to 400 - 600 Mbps when testing to the same computer's hard drive!
LST Server uses port 4456 by default. If it is necessary to change ports, first change ports on the LST Server (instructions are in that program), then change the 'TCP Port' (just above the 'LST server IP:' option) with the correct Port number.
Also, with this feature, it is now possible to test computers over a WAN (internet) connection to get your internet speed! LST Server uses port 4456 by default. Further instructions for testing your internet speed is beyond the scope of this help file. Go to our website for more information.
