测试环境是建立在虚拟PC上的,执行ApacheBench的是宿主,虚拟PC软件是用微软的VPC,上面装了WIN2003简体,RAM是共享宿主的512MB

宿主的配置是:T2400 1.8G 2.5G RAM

———————————————————–

本次测试是针对在没有微软官方的FASTCGI之前在IIS上使用PHP(不论是ISAPI方式或者CGI方式),在高负载和长期运行后不稳定的问题进行的,本次测试目的主要是检查FASTCGI PHP的稳定性

———————————————————–
被测试的PAGE只是一个phpinfo()调用.

使用的是ApacheBench模拟30个并发,执行1000000次请求,结果请看下面.
在三个半小时(214分钟)的整个测试过程中没有出现任何异常,测试完毕后RAM也被正常释放.

fastcgi testing

PS.在测试期间宿主上面还打开多个聊天软件并且打开多个IE在进行浏览网页

hp-cgi.exe进程

FASTCGI的配置如下

PHP=C:\PHP\php-cgi.exe
[C:\PHP\php-cgi.exe]
QueueLength=1000
MaxInstances=4
InstanceTimeout=30
InstanceMaxRequests=1000
