最近一个项目中，需要在asp/asp.net调用外部exe文件，代码测试无误后，部署到server(window server 2003)上，发现速度非常慢,执行时间一般14秒左右，同样的程序在beta环

境(window server 2003)和本机(windows xp professional)上执行很快 速度是300毫秒以内，我感觉非常奇怪，尝试了很多设置，问题还是不能解决，
我想应该不是权限的问题，如果是权限问题，结果应该是要么能够执行要么不能，现在的结果能执行，但是就是非常慢。

请csdn的朋友给些建议或思路 非常感谢！

在asp/asp.net情况都是如此，下面我把code,展示给大家，请予以诊断分析!
