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.
Performace and Stress Testing Tool
Javorský, Daniel ; Veselý, Vladimír (referee) ; Ščuglík, František (advisor)
This thesis is concerned about performance and stress testing of Xtend product developed by Xura, Inc. Software development knowledge, theoretical knowledge of testing and testing tools are described in opening chapters together with key features and services provided by Xtend. Emphasis was put on implementation of performance and stress testing tool, which focuses on short-term and long-term testing scenarios and output of this tool serves Xtend developers. Part of this thesis also focuses on results of stress and performance tests.
Performance Optimization of Testing Automation Framework Based on Beakerlib
Heger, Jakub ; Smrčka, Aleš (referee) ; Šimková, Hana (advisor)
Cílem této práce je analyzovat a optimalizovat výkon testovací knihovny BeakerLib, konkrétnělogovacího mechanizmu, který byl nahlášený jako problematický z hlediska výkonu. Prvníčást práce se zabývá analýzou daného problému, v druhé jsou popsány navržená řešení ajejich implementace. Na závěr bylo provedeno měření výkonu implmentovaných řešení abydošlo k ověření úspěšnosti. Tato práce byla řešena ve spolupráci s firmou Red Hat.
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.
Performance Measurement of Selected Drools Tools
Široký, Petr ; Fiedor, Jan (referee) ; Letko, Zdeněk (advisor)
Performance testing is often overlooked. This thesis describes the performance testing of the Drools Expert and Drools Fusion tools. Drools is a Business Logic Integration Platform. Expert and Fusion are parts of this platform, which provide rule based expert system and event processing capabilities respectively. Tests are designed and implemented with main focus on finding performance regression between different versions of Expert and Fusion tools. Results for two versions of these tools are discussed at the end of the thesis.
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.
Database Performance Tester
Šulaj, Martin ; Hujňák, Ondřej (referee) ; Očenáš, Martin (advisor)
Main goal goal of this project is to create tool for performance testing of relational databases and to prove his functionality. The tool is logically divided into 4 parts and every one of them can work independently. With the use of the tool we ca create, execute and evaluate test suites. Graphical visualisation of processed results is a part of the tool. The tool works with test suites that are executed on Raspberry Pi 3 B device and on well performing laptop. Databases that are tested with this tool are MySQL, PostgreSQL and SQLite.
SAP HANA Platform
Uhlíř, Michal ; Volf, Tomáš (referee) ; Zendulka, Jaroslav (advisor)
Tato práce pojednává o databázi pracující v paměti nazývané SAP HANA. Detailně popisuje architekturu a nové technologie, které tato databáze využívá. V další části se zabývá porovnáním rychlosti provedení vkládání a vybírání záznamů z databáze se stávající používanou relační databází MaxDB. Pro účely tohoto testování jsem vytvořil jednoduchou aplikaci v jazyce ABAP, která umožňuje testy provádět a zobrazuje jejich výsledky. Ty jsou shrnuty v poslední kapitole a ukazují SAP HANA jako jednoznačně rychlejší ve vybírání dat, avšak srovnatelnou, či pomalejší při vkládání dat do databáze. Přínos mé práce vidím v shrnutí podstatných změn, které s sebou data uložená v paměti přináší a názorné srovnání rychlosti provedení základních typů dotazů.
