Using wireshark to troubleshoot a slow file download
Figure 2: Use Wireshark’s Statistics > TCP Stream Graph > Round Trip Time Graph to determine the current roundtrip latency for a file download. We use Wireshark to determine the roundtrip time on a path to determine if this is the reason for poor net-work performance for Transmission Control Protocol (TCP) communications. TCP is used for web 5. Use File, Save as to create an analysis file in the specified format. Interpreting The Results. With the multitude of options it has to offer, it’s easy to get lost in the output from a Wireshark analysis. If you’re looking to diagnose a network problem, the key thing is to isolate the source of the problem traffic. The Statistics In this article, we use Wireshark, a free open source packet analyzer used for troubleshooting network issues. The focus of this article is to use it to analyze network performance for an environment where an instance of JasperReports Server is running, to see whether or not it is performing acceptably. In this video, we learn how to use the http.time filter in Wireshark to quickly identify slow application response time from web servers. This filter can be added as a button in the Wireshark profile. For example, if I said, “email is slow or it takes 2 hours to download my files” you have a chance to address this since I can measure the problem and the end result. The 2 hour comment
If there are no issues in the client, you should investigate potential network issues such as packet loss. You can use tools such as Wireshark or Microsoft Message Analyzer to investigate network issues. For more information about using Wireshark to troubleshoot network issues, see "Appendix 2: Using Wireshark to capture network traffic."

In this article I’m going to look at the most common Wireshark filters that I use when I’m troubleshooting mail flow with a network trace. In a previous life I used Wireshark to troubleshoot problems with video streaming, SOAP over HTTP, and server communications, which is why it is my go to tool for network captures.
