asp/asp.net下运行exe文件出现的一个奇怪问题

0
悬赏园豆:20 [已关闭问题]

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!
