Eine kleine, erfolgreich umgesetzte Idee kann jemanden zum Milliard\u00e4r machen, wie man an Menschen sieht, die mit nur einer Idee Geld verdient haben. Die Verbreitung von Technologien hat daf\u00fcr gesorgt, dass man \u00fcber Werkzeuge verf\u00fcgt, um seinen Ideen Gestalt zu verleihen. Wenn Sie eine Idee haben, brauchen Sie lediglich etwas Kapital. Sie brauchen nicht einmal viel Geld. Sie k\u00f6nnen Ihre Ideen ganz einfach auslagern und zu einem Bruchteil der Kosten umsetzen lassen. Anwendungen sind in der heutigen Gesch\u00e4ftswelt sehr wertvoll, insbesondere solche, die viel fr\u00fcher als \u00fcblich erstellt werden k\u00f6nnen. Da die Anwendung so schnell wie m\u00f6glich auf den Markt gebracht werden muss, verzichten viele Unternehmen auf die \u00dcberpr\u00fcfung der Anwendungsleistung. Eine schlecht ausgef\u00fchrte Anwendung kann sich negativ auf Ihre Website auswirken und Ihrem Markennamen schaden, ganz zu schweigen von Sicherheitsproblemen, enormen Umsatzeinbu\u00dfen und dem Verlust des Kundenvertrauens. Denn welche Vorteile kann es bringen, wenn eine Anwendung nicht richtig l\u00e4uft?\n\n<strong>Ruby-Prof<\/strong> ist ein Leistungsoptimierungstool f\u00fcr Ruby-basierte Anwendungen. Als C-Erweiterung ist es viel schneller als der Standard-Ruby-Profiler und unterst\u00fctzt sowohl flache als auch grafische Profile. Ruby-prof zeigt Diagrammprofile f\u00fcr jede Methode und zeigt, wie lange die Methode ausgef\u00fchrt wurde, welche Methoden sie aufgerufen haben und welche Methoden sie aufgerufen hat. Ruby-prof stellt sowohl Text als auch HTML bereit und kann ihn als Standardausgabe oder in eine Datei ausgeben. Dieses Ruby-Juwel kann verschiedene Parameter messen, darunter Aufrufzeiten, Objektzuordnungen und Speichernutzung. Da dieses Juwel die Profilierung mehrerer Threads gleichzeitig unterst\u00fctzen kann, ist es eine der besten Optionen f\u00fcr jede Ruby-basierte Anwendung. Ruby-prof kann jedoch nur auf Ruby-Version 1.9.3 oder h\u00f6her ausgef\u00fchrt werden. Wenn Sie Linux oder UNIX verwenden, ben\u00f6tigen Sie m\u00f6glicherweise einen C-Compiler, damit die Erweiterung bei der Installation kompiliert werden kann. Unter Windows m\u00fcssten Sie Windows-spezifisches Ruby Gem installieren und eine bereits erstellte Erweiterung integrieren.\n\n<strong>So installieren Sie Ruby-Prof Gem\u00a0<\/strong>\n<blockquote>git clone git:\/\/github.com\/jeremy\/ruby-prof.git cd ruby-prof\/ rake gem sudo gem install pkg\/ruby-prof-0.6.1.gem<\/blockquote>\n<strong>Einrichten einer neuen Umgebung f\u00fcr die Profilerstellung<\/strong>\n<blockquote>Erstellen Sie config\/environments\/profiling.rb: config.cache_classes = true config.action_controller.consider_all_requests_local = false config.action_controller.perform_caching = true config.action_view.cache_template_loading = true #config.log_level = :debug<\/blockquote>\nF\u00fcgen Sie die neue Umgebung zu \u201edatabase.yml\u201c hinzu. M\u00f6glicherweise m\u00f6chten Sie die Entwicklungsdatenbank wiederverwenden.\n\n<strong>Erstellen eines Profiling-Skripts:<\/strong>\n\nAls N\u00e4chstes erstellen wir ein Skript, das einfach die Homepage abruft. Speichern Sie den folgenden Code in profiling\/homepage.rb:\n<blockquote>get &#039;\/&#039; say \u201eGET \/ =&gt; #{path}\u201c<\/blockquote>\nF\u00fchren Sie das Skript aus.
