Impact of TCP/IP stacking on actual file transfer in Vista system

This blog login system was completed by Microsoft's team responsible for the TCP/IP enhancements of the Windows Vista/Longhorn operating system.

"Our team has been testing and sampling the server version of Longhorn for a while, and we are very interested in the networking features. Especially the changes in the TCP/IP stack in Vista and Longhorn. We know this It will affect the back-end operations of the system to a large extent, such as data transfer between data centers, but we also believe that the front end including the Vista download function will be greatly improved. This means that you will be able to enjoy at home or in the office. High-speed downloads, unless your network has bandwidth limitations."

Windows Network Group Let us help test the data center TCP/IP stack to get some real-world data, this is our first attempt on the TCP/IP stack.

Now, TTCP is constantly challenging the limitations of stack, cpu, bus, network, etc., but it has not affected the file transfer that occurs in actual work.

Since these file transfers have brought us more challenges, we have placed two new servers in Washington and California, each with a GigE NIC. Each data center has a W2K3 server and a Taiwan Longhorn Server.

We set up two automated tasks to transfer 201GB files from the California server to the Washington server vendor. These two automated tasks are run by W2K3 and Longhorn systems respectively. The servers are HP DL385 dual-core 16GBRAM memory and GigE network. The experimental results are:

The file transfer task using W2K3 system has a speed of 12Mb/s.

Using Longhorn The speed of both ends of the file transfer task performed by the system exceeds 400Mb/s

and the speed of Longhorn system transferring 1GB file in the same virtual LAN is about 502Mb/s
