Orite Blog

Since Internet Explorer8 has just joined the infamous IE family, which added bit of work (chaos) in the compatibility war. We have designed the following tool to show the difference between the "recent" IE versions, namely 6,7 and 8. Hope this would help web developers who care about browser compatibility.

We have done enough reading and digging on the net just to see how others test and compare PHP frameworks, however there are hardly anything recent and convincing. Most of the test are on throughput of a simple 'Hello World' page, which we don't think reflect the real performance of a framework, simply because no Database interaction was involved, hence Model as in MVC is not tested at all. So we decide to conduct our own test with a more real world case, which would require MVC work together intensively to get up the result.

The Test

We have each programmer picked a popular PHP framework, and the task is to setup the framework and create MVC for the benchmark, which involves,

• 1000 database insertion
• 1000 database update
• query 1000 records (all fields), and display in a list
• each record size is about 2kb

We then put all the coded project onto one work station which has the following configuration,

• Pentium 4, 4.3GHz
• 2GB RAM
• Windows XP, SP3
• XAMPP 1.7.0 (patched to work with PDO)
• APC enabled (Zend Optimizer disabled)
• All programs turned off, including Anti-Virus and Firewall

We use a PHP batch script under CMD to make queries to each framework 10 times, and reports on the average response time and memory usage.

The Result

Framework	Database Engine	Avg. Response Time	Avg. Memory Usage
Pure PHP	mysqli	5.28s	0.14MB
oModel*	adodb mysql	7.13s	6.88MB
Yii Framework (yiilite)	pdo_mysql	7.41s	8.38MB
Yii Framework	pdo_mysql	7.7s	9.44MB
Kohana	mysqli	7.68s	11.22MB#
Zend Framework	pdo_mysql	8.37s	7.99MB
Zend Framework	mysqli	11.28s	7.88MB
Akelos	mysqli	12.98s	10.93MB

* The Orite in-house lightweight MVC framework
# With <benchmark> parameter turned off in the database config file, it only uses 1.5MB memory, and takes about 7.8s. Thanks Jeremy Bush for the advice. (updated 24/07/2009)

The Verdicts

Framework	Pro.	Con.
oModel	Fastest framework, light file structure, highly flexible, real short learning curve	Not as comprehensive, not well documented, no community support, need high skill set to work on for large-scale project
Yii Framework	Fast, comprehensive, simple and secure file structure, strictly php5 OO, well documented, code generation	Farely new, still building community awareness
Kohana	Flexibility, Easy start	Big memory footprint, DB feature incomplete
Zend Framework	Great library set, flexible, best community support	Long learning curve, code generation problem*
Akelos	Great RoR port, database migration	Slow, php4

* We have try to run Zend-Tool on two workstations, all failed to run

The Conclusion

We understand this benchmark comparison is still bit off the real world, as it has too much emphasis on the database operation, where as in real web scenario the result can vary on different server deployment. Also, we didn't test cache mechanisms under each framework, which would play a real important role in the production environment, when server gets lot of hits on dynamic content, the result can be really different depend on project nature. Hopefully Orite will further test  real web project taken most the core features of frameworks in consideration. If we were after speed, we would stick with oModel which had been the backbone of lots of recent Orite projects. After testing the frameworks, our team had picked both Zend Framework which has the most supportive community and feature set, and Yii Framework the good combination of comprehensive feature, ease of use and performance. We will start few project based on Yii Framework and continuously keep eyes and hands on Zend. Interesting findings regarding this topic will be posted after we have dived into these frameworks a bit more.
