 <h3> Understanding the test results </h3>
 <p>
 End-to-End performance depends upon a number factors.  One of the biggest  
factors
-is setting the tunable network parametes to the proper value.  There are  
several
-web sites that provide detailed tuning instructions for various Operating  
Systems.
-Two of the best are:

-<li><a href=http://fasterdata.es.net/TCP-tuning>ESnet's TCP Tuning  
Guide</a></li>
-</ul>
+is setting the tunable network parametes to the proper value.
 The throughput an application achieves is dependant 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

default buffer size</a>
-on your computer.  Win 95/98/NT users can easily set and change their  
default buffer size
-by using the <a href="http://moat.nlanr.net/Software/TCPtune/";>TCPtune  
application</a>

 Max window used to be 64KB, but newer OS's now support window scaling,
 so you may be able to request more than 64 KB.
