Objetivos del curso

This class teaches seasoned Wireshark users how to identify performance problems. While analyzing a complex, mashed network and multi-tier Client-Server architectures the class introduces techniques to identify performance problems. With a lot of practical exercises students identify latencies of network links and active components. The class demonstrates the effect of typical misconfigurations and misconceptions in applications, servers, workstations and networks. Students learn to combine Wireshark with a spreadsheet application to calculate precise response times and present them as meaningful charts.
