这样硬件配置的服务器，apache 能并发多少个连接？ ？

miniweasel

5620*2 双四核 虚拟16线程
内存24G 硬盘SAS RAID1。
Freebsd 8.2 apache php5 mysql
只有一个ecshop的商城。开发了伪静态

配置好了。应该能够并发多少个链接呢？

我ab 100用ie打开网页就很慢了。
ab200 直接显示无法连接数据库。

我晕 不是吧   当时系统有啥负载吗？

miniweasel

什么也没有。就是一个干净的freebsd。除了常用的都没装。只提供 apache mysql php。

1009831107 我的QQ。能否请教一下


600压测的时候用浏览器打开主页。ECSHOP info: Can't Connect MySQL Server(localhost:3306)!

只有一台主机和服务器接在一个路由上。

装个webbench，测试一下，不太喜欢apache自带的ab工具，觉得有时候不准
