1: TCP Throughput of Five Microsoft Windows

At packet sizes between 64 bytes and 256 bytes, the difference in throughput between all five Microsoft Windows operating systems is less than 0.2%.

Therefore, between packet sizes of 64 bytes and 256 bytes, the TCP throughput

of the five Windows operating systems is similar in both IPv4 and IPv6 networks.

2. From packet sizes of 384 bytes to that of 1536 bytes, Windows XP has higher TCP throughput than the other Windows operating systems

the exception of 768 bytes, for which only Windows 7 has higher throughput).

3. From packet sizes of 1024 bytes to 1536 bytes, Windows 2003 has lower TCP throughput than other Windows operating systems in both IPv4 and IPv6 networks.

The following line chart is an enlarge

of three Windows client operating systems with packet size of 384 bytes to 1536 bytes in both IPv4 and IPv6 networks.

From above line chart, the following conclusions can be made:

1. At packet size of 768 bytes, Windows 7 has higher TCP throughput than other Windows operating systems

2. From packet sizes of 384 bytes to 1536 bytes (with the exception 768 bytes as in point 1), Windows XP has higher TCP throughput than other Windows operating systems in IPv4.

3. In most packet sizes, Windows Vista has lower TCP throughput than other operating systems in both IPv4 and IPv6 networks.
