升级PHP 5的理由:PHP 4和PHP 5性能对比(1)

php for upgrade and Compared Will performance support of conduct

PHP 4到07年年底PHP Group将不再对其进行支持了,所以为了让大家更有信心的转移到PHP 5平台上,我特别做了这个测试,看看我们PHP 4.x是否真的性能比我们的PHP 5.x要好呢!测试结果很明显,那就是PHP 5.x比php 4.x不论是面向对象还是面向过程,都要比PHP 4.x要快,所以大家完全有必要转移到PHP 5.x平台上,去体验PHP 5.x平台的各种功能和性能。

因为PHP 5包括新的对象模型,更多新特点,更快的处理速度,特别是处理面向对象代码的速度,虽然在php 4中面向对象代码的速度比较一般,但是在PHP5.x中面向对象代码的速度都超过了面向过程的速度,所以不要对面向对象的性能持有怀疑,下面的测试结果将说明这一切。

测试环境

CPU Intel Pentium4 2.66GHz
Memory 1GB
Disk 73GB/SCSI
OS FreeBSD 4.11
Web Apache 1.3.37
测试工具 ab(也可以选用http_load)
名词RPS Requests per second(每秒的请求数量)
