我用的是VPS服务器，内存1G ECC，双核CPU，70G硬盘，3M独享带宽，四线，WIN2003系统
因为网站还在内测中，所以同时在线人数不超10人
现在网站用一会就卡，而且卡几分钟，有时候卡住不动，需要重新打开网页登陆，我问服务器商，他们说是硬件配置太低了，卡的时候CPU占用率突然很高，需要升级服务器，而我怀疑是系统的问题，请问这种情况到底是系统问题还是硬件问题？
回复讨论(解决方案)
PHP代码，程序在本地测试一点都不卡
要看看什??程占?源。
看情?服?器足?了。
这配置 上Linux 看看...不过就几个人的情况 按道理不应该这个样子的
求网址。~~~~~~~~
可能是 vps 超售了
如果是openvz 可以超售
xen kvm 不行
看看是属于哪种虚拟技术。
再看看自己在vps 上执行的时间
麻烦你看看这个。。。 http://www.bo56.com/%E5%96%84%E7%94%A8php-fpm%E7%9A%84%E6%85%A2%E6%89%A7%E8%A1%8C%E6%97%A5%E5%BF%97slow-log%EF%BC%8C%E5%88%86%E6%9E%90php%E6%80%A7%E8%83%BD%E9%97%AE%E9%A2%98/
如果有查询，可以看下当前页面sql，这个有可能是带宽的原因。
先用浏览器查查看看是卡在哪个元素上了 然后再在后台打到对应的元素查看性能瓶颈在哪
换了LINUX系统后就好了，谢谢大家
