You can test the reliablity and operational status of your desktop computer and network connection in about 20 seconds with the Web100 based Network Diagnostic Tool (NDT).
The NDT performs 2 throughput tests between your desktop computer and the NDT server. First, data is streamed for 10 seconds from your desktop to the server and then a second 10 second test is performed in the opposite direction. A Web100 modified linux kernel captures detailed statistics on these TCP data flows. This data is then analyzed to determine why the connection achieved the throughput results it reported.

And what’s more, you can learn how to tune your system to speed up your connection. The throughput an application achieves is dependent on
- the amount of buffer space available in the sending and receiving hosts,
- packet loss due to errors or congestion,
- packet size (usually limited to 1500 bytes by Ethernet), and the
- round trip time between the 2 hosts.
If this test reports that the sender or receiver buffer size is the limiting factor, increase the buffer size by changing the default buffer size on your computer.
There are several web sites that provide detailed tuning instructions for various Operating Systems. Two of the best are:
These work, and quadrupled the speed of AmCham Vietnam’s internet connection, just by changing the buffer size.
