在Windows上使用mysql和apache的性能问题

标签： php mysql windows apache performance

没有人知道什么可以帮我找出这个问题的原因???

我为一个非营利项目写了一个网络应用程序。我们每年有两次市场，我们出售二手儿童服装和玩具。人们带给我们他们的货物，我们管理所有的销售，并为我们镇上的儿童项目收取费用。

我的脚本和数据库工作正常，但我遇到了一些性能问题。我们可以做5-10预订没有任何问题，脚本挂起。我们通过扫描条形码（脚本1）进行预订。脚本2正在寻找合适的价格并在mysql数据库中写入一个条目。如果我们没有问题，请在扫描后（不到一秒钟）完成预订。

我的问题是，我不知道我们遇到问题的地方。

如果我只在我的localhost上测试应用程序，我看不到任何问题而且它没有挂起。仅在通过网络连接时。然后，我可以做10次预订，然后突然停止在后台工作/加载。刷新页面后，它再次开始工作。我不确定问题是apache或mysql-server还是脚本。也许我有网络问题？

有谁知道如何找出导致性能问题的原因？

服务器？阿帕奇？ MySQL的？ 路由器？开关？ 客户端？

提前一千万次感谢您的所有帮助和帮助？

我们在一秒钟内做3-4次预订。使用所有计算机并且使用五年或更长时间（也是服务器）。它是1台服务器和3台客户端计算机（所有Windows 7 Pro）。我使用chrome作为浏览器。我有一个路由器和一个非管理型交换机用于网络连接。网络中没有其他计算机。

这是预订的两个php脚本：
