TCP/IP Network Performance

  • Article

Applies To: Windows Server 2008 R2

Network performance encompasses all aspects of data transfer performance, such as download and upload speeds, number of packets dropped versus packets delivered, and the round-trip time of connections.

These aspects of network performance might be affected by congestion in the network. In the case of wireless networks, signal attenuation, electromagnetic interference, and the mobility of the host also affect network performance.
