Overview: It is clear that packet loss makes a major contribution to lowering the TCP throughput and effort in working with campus network engineers to reduce this is worthwhile. This research paper shows that the advanced TCP stacks recover much faster from the effect of packet loss and this is much more important for longer RTTs. This paper also reports on investigations of the performance of TCP stacks and their use with data transfer applications such as GridFTP, bbftp, bbcp and Apache and effects of the Network Interface Card, NIC, the PCI bus, and the disk and RAID subsystems.
