VPS究竟行不行？ 感觉比虚拟主机还差！！！

minglwm

我最近购买了LP的VPS主机（512MB）
使用了发现apache 的maxclient默认是10, 我把它设到80，都扛不住了，高峰期根本打不开，内存耗尽。

我的VPS怎么就没有想像那么好？

以前在hostgator差不多一万IP才给K掉了，现在都不足3K 日流量，都扛不住了

谁可以分享一下VPS的经验？

LP客服建议我最多只能设到20-25，慢！

吧keepalive关掉,或者不关keepalive,把keepalivetimeout设小点,5以下,试试.

已经关掉，而且 超时为 3

同意，vps就是这样

晕  看来vps也不是那么省心....
难道要我勒紧裤腰带 奔向我的服务器？

毕竟一个服务器装了数个系统,数个apache,数个mysql,不像虚拟主机只装一个大家共用.
特别是unmanaged vps需要自己做大量优化.
