A presentation given at Connect 2017 described thus and In this presentation, we present Fedora 4’s performance in different use cases. These use cases are the most general use cases that were developed by the Fedora 4 performance team. We compare the performance between different versions of Fedora 4 and demonstrate the improvement between these versions. We will also describe the procedures of these performance experiments and demonstrate the software we use (Ansible, AWS, and JMeter). Our performance experiments are conducted in the AWS ecosystem, and we use an R graph tool to visualize the JMeter result. With the AWS grant, we can do many different performance experiments in many scales. Moreover, it is easy to repeat and verify the performance results using AWS. The Fedora 4 performance team wants to know more about the Samvera community’s interests related to the Fedora 4 performance. We plan to gather more use cases from the Samvera community, including middleware such as Solr, Camel, and Fuseki, etc. We can investigate, explore issues, and continue enhancing the future of Fedora 4.
