Parallels lässt auch mal wieder von sich hören. Für mich allerdings uninteressant. VMWare Fusion hat sich gegenüber Parallels um einiges stabiler erwiesen. Von den Features her hat es Parallels ja schon länger überholt...

Ich habe mich in letzter Zeit etwas nach Frameworks für die Applikationsentwicklung in PHP umgesehen. Hintergrund ist die anstehende Entwicklung einer etwas grösseren Anwendung. Das Framework sollte den MVC-Pattern umsetzen, eventuell Hilfestellungen bei Routine-Tasks geben, aktuell sein (weiterentwickelt werden) und vor allem sollte die verfügbare Dokumentation umfangreich sein.

Nach kurzer Zeit musste ich feststellen, dass die Auswahl sehr gross und unübersichtlich ist. Bisher habe ich mich nicht entschieden. Vielleicht hat der eine odere andere Leser Erfahrungen mit einem dieser Frameworks und möchte sie mit mir teilen? Ausserdem mag ich mit diesem Überblick die Leute unterstützen, die vor einer Ähnlichen Entscheidung stehen.

Es handelt sich hierbei wirklich nur um einen Überblick und keine Bewertung. Es werden die mir bekannten Frameworks mit der Beschreibung von ihrer Webseite verlinkt.

Nach einem apt-get upgrade und den darauffolgenden PHP-Update durfte ich mal wieder eAccelerator neu kompilieren. Ich dachte mir wenn ich schon mal dabei bin, kann ich gleich die aktuellste Version installieren (0.9.5-beta2). Gedacht - getan; wie erwartet gab es dabei keine Probleme.

Heute bin ich auf die Idee gekommen, mal wieder den Zend Optimizier™, mittlerweile Version 3.0.0, zu testen. Zum Benchmarken habe ich wie immer ApacheBench (ab) verwendet.
Der Benchmark wurde mit http://masterbootrecord.de/index.php (selbstgestricktes CMS) und einer VBulletin-Installation (3.5x) mit einigen Umfangreichen Hacks durchgeführt. Beide liegen auf diesem Server.
Die Umgebungsdaten: PHP Version 4.4.2, Apache/1.3.34, MySQL 4.1.15
"ab" wurde mit folgenden Parametern lokal auf dem Server gestartet: -n 1000 -c 10 -k (1000 requests, 10 parallel, Kepp-Alive on)

Hier das Ergebnis für eAccelerator:

Fazit: Mit eAccelerator gelingen fast doppelt soviele Requests als mit Zend Optimizer! Klarer Sieg der OpenSource-Software!
