NTttcp and NetCPS network test tools

From time to time I need to test the network connection between two windows machines and need to get some kind of report. One other thing important when testing is to define some basic parameters for a test scenario e.g. amount of data for transfer, duration of testing etc. In this type of tests, Windows 7 or Windows 2008 network connection information/diagnostics doesn't help me a lot (although Windows Performance could help). I searched through the internet for a small application which doesn't need any installation and can be run on the most windows systems. I liked two tools.
One is NTttcp which is a multithreaded, asynchronous application that sends and receives data between two or more endpoints and reports the network performance for the duration of the transfer. It is essentially a Winsock-based port of the ttcp tool that measures networking performance in terms of bytes transferred per second and CPU cycles per byte. Because it can be difficult to diagnose a system's overall performance without dividing the system into smaller subsystems, NTttcp allows users to narrow the focus of their testing and investigation to just the networking subsystem.
One other tool I found useful and easy to use was NetCPS which is similar to NTttcps but has a simpler report which is ok in most cases.

Here are sample reports from these two tools:

For NTttcp report looks like this:

C:\Program Files (x86)\Microsoft Corporation\NT Testing TCP Tool>NTttcpr -m 1,0,

For NetCPS report is a bit simpler:
