Unix Tools for Application and System Profiling
Dressler, David ; Chalupníček, Kamil (referee) ; Kašpárek, Tomáš (advisor)
The main goal of this thesis was to demonstrate usage of tools for application and system profiling. Initially, these tools was found and studied. They was also divided into categories according to their purpose. After that, these tools was compared according to their complexity of use and invasiveness. As the result of this comparison, these tools was divided into three groups, that express measure of complexity and invasiveness. As technology, used for creating models, was chosen Apache server and NFS server. Virtualization by hyper-v technology was used for putting these models into operation. There was created four virtual machines. Fist one for Apache server, another one for NFS server. Third was for mirroring content of Apache server and the last one for load generation. The last part of this thesis was to demonstrate usage of found tools on the created models.

PerfJavaDoc: extending API documentation with performance information
Náplava, Jakub ; Horký, Vojtěch (advisor) ; Hnětynka, Petr (referee)
Javadoc is a documentation tool used for generating API documentation from Java source code. For some methods the generated documentation can contain description of the algorithm and its asymptotic complexity. However, such information is futile when the exact execution time of the method is needed with respect to certain critical characteristics. In this work we decided to enhance the Javadoc tool with a performance extension which permits to measure the performance of the method against the predefined characteristics. These characteristics are specified in a workload generator, which is a method used to prepare the actual arguments and instance for the measured method. The separation of the measured code and the preparatory code allows developers to implement both parts clearly and easily, and also share the generator amongst multiple methods. The measuring itself is performed by a measuring server which may run on a dedicated reference machine, and was programmed to provide accurate results with respect to the Java platform.
