Troubleshooting Slow FTP Performance on a Gigabit Ethernet Network
Question
A server is connected to a gigabit Ethernet switch and has negotiated 1Gbps / Full Duplex.
When transferring large files to and from other servers on the segment via FTP slow performance is noticed.
All network cabling, network hardware and server hardware were verified to be working correctly.
Which of the following could be done to improve performance?

A. B. C. D.C.
The most likely cause of the slow performance is network congestion or packet loss, which can result in a decrease in TCP throughput. One of the ways to improve network performance in this case is to increase the TCP window size.
TCP window size refers to the amount of data that a server can send before it expects an acknowledgement from the receiving device. A larger TCP window size means that more data can be sent before waiting for an acknowledgement, which can increase the efficiency of data transfers.
Therefore, option C is the correct answer: Increase the TCP window size.
Option A (Decrease the TCP window size) would further decrease the amount of data that can be sent before waiting for an acknowledgement, making the problem worse.
Option B (Increase the UDP window size) is not relevant in this case, as UDP does not use a window size for flow control.
Option D (Decrease the UDP window size) is also not relevant, as UDP does not use a window size for flow control.
It's worth noting that increasing the TCP window size may not always solve the problem, as other factors can also contribute to slow network performance. However, it is a common solution for improving TCP throughput.
