Nginx+PHP(FastCGI)测试

ddlddx0000

基本环境


单台1G内存兼容机

环境Nginx+ PHP(FastCGI)

在5000并发连接，开启的10个Nginx进程和20个php-cgi进程下，测试出效果很不寻常:)

在Completed 3000 requests时随机监控了nginx活动状态和机器负载


>1.Nginx运行状态
Active connections: 4222
server accepts handled requests
30589 30589 30609
Reading: 1 Writing: 4221 Waiting: 0



监控显示对后端发起的活动连接数Active connections:4222


nginx 总共处理30589个连接, 成功创建 30589次握手 (证明中间没有失败的), 总共处理了 30609个请求


nginx 读取到客户端的Header信息数1

nginx 返回给客户端的Header信息数4221

Nginx等候下一次请求指令的驻留连接0
