A Comparison of a Performance of Different File Systems
Beňas, Petr ; Kašpárek, Tomáš (referee) ; Smrčka, Aleš (advisor)
The aim of this work is to compare the performance of common local filesystems used in GNU/Linux operating system. State-of-the-art filesystems together with existing benchmarks are described. The work also describes in detail the hardware used for performing benchmarks and the settings of the operating system. A tool for the analysis of benchmarks performed by the Iozone tool has been developed. Finally, the analysis and the discussion upon the results of Iozone and Postmark has been made.

Unified Reporting for Performance Testing
Kůrová, Martina ; Vojnar, Tomáš (referee) ; Šimková, Hana (advisor)
Moderní pokrok v oblasti technologií pro vývoj dnešních softwarových aplikací umožnil vývojářům více se soustředit na vývoj funkčnosti aplikace na úkor sledování jejího výkonu a správy zdrojů. V důsledku toho se zvýšily požadavky na nástroje pro výkonnostní testování, které by měly poskytovat vývojářům jasný a srozumitelný přehled o stavu systému z hlediska jeho výkonu a umožnit rychlou interpretaci naměřených výsledků. Tato práce zkoumá typické výkonnostní problémy dnešních aplikací a navrhuje přístupy, pomocí kterých je možné tyto anomálie automaticky rozpoznat. Pomocí statistických metod, jako je regresní a korelační analýza, je provedena analýza dat naměřených během výkonnostního testování s cílem rozpoznat ve výsledcích odchylky od normálního chování a z nich identifikovat výkonnostní problémy. Výsledkem je report o celkovém stavu systému z hlediska jeho výkonu. Implementací regresní analýzy je možné detekovat výkonnostní problémy jako je například zhoršující se reakční čas odpovědi, nízká propustnost systému či odhalit únik paměti. Navrhovaný přístup byl implementován v podobě nové komponenty v open-source nástroji pro výkonnostní testování PerfCake. Vyvinutá komponenta je schopna detekovat a reportovat potenciální výkonnostní problémy a jejich pravděpodobnost.

Performance Monitoring of MES PHARIS
Ondráček, Aleš ; Hruška, Martin (referee) ; Smrčka, Aleš (advisor)
This diploma thesis deals with the performance monitoring of automated development processes and performance testing of the MES PHARIS system. The main scope of thesis is the collection of data on tasks performed on automation servers DevOps and Jenkins, processing of this data and their subsequent visualization. The second part of the diploma thesis deals with the processing of data from performance testing and their appropriate representation using visualization. The core technology that is used is ELK Stack.

Performance Data Collection of MES PHARIS
Oháňka, Martin ; Hruška, Martin (referee) ; Smrčka, Aleš (advisor)
This master's thesis deals with monitoring of automated tasks on integration servers and obtaining data from these tasks. Another area of this work is performance testing and to obtain information about hardware utilization from it. Thanks to this, it is possible to perform performance analysis of the implemented solution from different performance perspectives. The result of this master's thesis is a software solution that can obtain data about tasks from DevOps and Jenkins integration servers. In the area of performance testing, there is created a solution for parallel execution of tasks. The output of this work an output passed in JSON format. The data is then transferred to the Elastic platform, specifically Logstash, where it is subsequently visualized using Kibana. The Beat platform is used to collect data from performance testing. The solution was applied to the production information system MES PHARIS of the UNIS company.

Java.math Package Benchmark
Frýz, Pavel ; Letko, Zdeněk (referee) ; Dudka, Vendula (advisor)
The aim of this work is to compare the performance of different implementation of java virtual machine, when using package java.math. The classes BigInteger and BigDecimal are described. Existing benchmarks for measuring the performance of a java virtual machine are also described. The work also describes in detail the hardware and operation system used for performing benchmarks. A tool for the benchmarking performence of implementation of classes BigInteger and BigDecimal has been developed. Finally, the analysis and the discussion upon the results of benchmarks has been made.

Nitrate Client Performance Improvement with Cache Implementation
Holec, Filip ; Letko, Zdeněk (referee) ; Müller, Petr (advisor)
The goal of the thesis is to design and implement performance improvements in python-nitrate module. Performance improvements are based on gathered use cases, which use large amount of data and network bandwidth. Performance test suite was implemented in order to measure impact of changes in module. Testing proved, that python-nitrate module with integrated performance improvements is in certain cases several times faster, but also can be slower in two cases. Discussion regarding possible extensions is present in the conclusion.

Performance Analysis of C# Programs
Hájek, Vojtěch ; Rogalewicz, Adam (referee) ; Pavela, Jiří (advisor)
The goal of this thesis is to extend the Performance Version System – Perun by implementing a module for profiling programs written in C# language. This extension implements a tracing profiler with the use of .NET runtime profiling aplication interface. Profiler can collect metrics about trace functions and memory consumption. Measured profiles can then be interpreted into graphs like a scatter plot or a treemap.

Výkonnostní a regresní testování nástroje Zoner Photo Studio X
Konopík, Matěj ; Kočí, Radek (referee) ; Smrčka, Aleš (advisor)
This thesis deals with the problematics of testing the manipulation of RAW format files from the modern digital cameras in Zoner Photo Studio X. Automatic regression tests are used together with the grey box method to continually control the quality of the output image date. A new testing system was created that is used to test the RAW conversion module. This system brings and open interface to easily and quickly integrate new image data tests, It also features automatic launching, analysis and reporting of the results. Thanks to this new system, the implementation of new test will become much easier and this will moreover increase the quality of the product.
