Network Tuning

One of the principle causes of poor data transfer performance is packet loss between the data transfer client and server hosts. There are many possible causes of packet loss, ranging from bad or failing hardware to misconfigured hosts or network equipment. Network design, coupled with proper configuration of hosts, routers and switches, can eliminate packet loss and result in significantly improved data transfer performance.
