Performance Analysis of Go Programs
Nešpor, Andrej ; Malík, Viktor (referee) ; Pavela, Jiří (advisor)
The goal of this thesis is to extend the performance versioning system Perun by implementing a module for profiling programs written in the Go language. This module implemets the profiler by instrumenting function calls and returns using eBPF technology. The tool can collect function run times and their traces. We can then interpret the outputted profiles as a Sankey diagram. Additionally we implemented a new way of visualizing the measured data using the so-called Sankey graph, which will help with their interpretation. Using the developed profiler we conduct a few experiments to verify its functionality and demonstrate its use.

Optimization and testing of the frontend on the Smart City platform
Špaček, Ján ; Hynek, Jiří (referee) ; John, Petr (advisor)
Cílem této práce je ve spolupráci s firmou Logimic vytvořit prostředí pro automatizované testování uživatelského rozhraní a výkonu platformy ACADA. Dalším cílem je odhalit problematické části platformy způsobující omezení výkonu a navrhnout optimalizace. K~dosažení stanovených cílů byl analyzován aktuální stav testování ve firmě a navržen nejvhodnější softvér pro testování. Výsledkem práce je soubor testů imlementový v knihovně Cypress, umožňující časnou identifikaci problémů v procesu vývoje. Využitím schopností knihovny Cypress zajišťuje tento soubor testů rychlejší a efektivnější postup testování a přispívá také k spokojenosti uživatelů zajištěním spolehlivosti a respozivity.

Design and implementation of a digitally signed report in the Apache JMeter
Procházka, Martin ; Člupek, Vlastimil (referee) ; Šeda, Pavel (advisor)
This thesis focuses on the development of a plugin for Apache JMeter to automatically generate report from the results of performance testing provided by other modules. In the theoretical part, it discusses the capabilities of Apache JMeter, stress testing in general, the structure of PDF document, the theory of digital signature and relevant cryptographic requirements. The practical part deals with the implementation of the report generator. First, it introduces the content of the report, then it discusses the principles of HTML and PDF report generation. Finally, the paper discusses the insertion of a digital signature into a PDF document.

Advanced Interpretation of Software Performance Changes
Kraus, Lukáš ; Rogalewicz, Adam (referee) ; Pavela, Jiří (advisor)
The aim of this work is to create an advanced algorithm for identifying suitable versions of a project in order to identify performance changes and errors. For this purpose, the Pe- run tool (developed within the VeriFIT research group), version management systems, methods for tracking performance changes between individual versions and display opti- ons for interpreting results are described. Analysis of the source code, detection of changes between versions, evaluation of changes according to rules, decision calculation whether versions are suitable for performance testing, and interpretation of results on a web page were designed and implemented in Python.

Java Collections Performance Testing on Multicore Systems
Husar, Martin ; Müller, Petr (referee) ; Letko, Zdeněk (advisor)
This thesis deals with Java collections performance testing on multicore systems. The aim of the work is studying of core collections contained in Java Collection Framework and studying also some other collections from package java.util.concurrent and third-party project known as Javolution. The task was to suggest appropirate performance test for these collections and create based on its results a comparison. Afterwards the basic solution is an implementation of suggested tests in Java programming language and evaluation of achieved results.

Performance Analysis of Programs Based on PIN Framework
Močáry, Peter ; Fiedor, Jan (referee) ; Pavela, Jiří (advisor)
Cieľom tejto práce je rozšíriť výkonnostný verzovací system - Perun implementáciou nového Tracer engine využívajúceho inštrumentačný nástroj PIN. Toto rozšírenie implementuje základné funkcie Tracer modulu a zároveň zber argumentov funkcií spolu so zberom dĺžky behu základných blokov programu. Tieto nové údaje spolu s vizualizáciami vytvorenými v tejto práci poskytujú potrebný kontext, ktorý zjednodušuje odhalenie zhoršenia výkonu. Okrem nástroja PIN využíva Tracer engine python knižnicu pyelftools na analýzu ladiacich informácií vo formáte DWARF pre zistenie podrobností o argumentoch funkcií pred procesom zberu údajov. Výsledný engine bol testovaný na viacerých implementáciách triediacich algoritmov a úspešne detekoval časovo najnáročnejšie funkcie spolu s informáciami o zvýšenej zložitosti súvisiacej s jej argumentom. Testovanie na projekte väčšieho rozsahu odhalilo, že v porovnaní s ostatnými implementáciami Tracer engine, tento nový engine pracuje lepšie alebo porovnateľne a produkuje správne výstupy.

Methodology for testing the security and performance of firewalls
Sasko, Dominik ; Člupek, Vlastimil (referee) ; Frolka, Jakub (advisor)
This bachelor thesis focuses on analysis of security and performance of firewalls and designing a methodology for testing them. Theoretical part is devoted to explaining firewalls and its' division and describing functions of next generation firewalls. Beginning of practical part focuses on testing security using penetration programs and shows results of each security test. Practical part continues with performance tests in various scenarios using Spirent Avalanche and compares the results with values stated by the manufacturer of firewall Hillstone.

Lombok Framework Study
Paštrnák, Ján ; Müller, Petr (referee) ; Letko, Zdeněk (advisor)
The aim of this thesis is to analyze Lombok framework and its usage for the development of Java programs. Framework Lombok enables the generation of a primitive, often repetitive code during compilation of the annotated code. Using annotations, programmer specifies what and where the framework needs to generate during the compilation. This thesis explains the basic principles of the framework and design tests that demonstrate practical aspects of its use for creation of Java programs. Emphasis is placed on the estimation of the time saved through the development of Lombok, study its influence on the process of compilation and testing framework integrity with three development environments - NetBeans, Eclipse and IDEA InteliJ. The thesis summarizes the pros and cons of using this framework in real work.
