This thread can be an opportunity to clarify the issue of "Network Speed" as measured in small LANs.
The kind of software like the above posted Netspeed, measures the traffic "speed" through a specific computer that it is installed on (nothing to do with other LAN computers). In addition it is measuring the "Speed" while you are using a specific application.
In other word, if you are using Internet Explorer you can see the speed of the traffic while you Surf or Download, this represents the traffic using this specific application in conjunction with your hardware. You can measure in this way the transfer between two computers while using ftp as oppose to using Windows Explorer etc. However such a method does not measure the "raw" capacity of your Hardware.
On the other hand Qcheck by NetIQ serves as a benchmark of LAN performance.
The software has two parts: The main program, and a client program.
You install the main program on your server, or what you consider as your main computer. Than install the client on the rest of your LAN computers.
Qcheck measures the interaction between the main program, and the client on another computer. No other applications are involved, thus providing you with a real representation of your Network Hardware Capacity.
I use Qcheck on every newly Network connected computer, following the initial connection, to make sure that the connection is optimal. I rarely find a need to use it later on.
By using Qcheck you can debug and improve your LAN.
Both program are valuable, but for different purposes.
The majority of the freeware "Speed" programs that are offered on the Internet are of the Netspeed type.
Qcheck is quite unique (being free offer) in its category.
