我有一个asp页面访问c ++代码并获取返回的xml字符串.每当我访问网页时,我都会在网络浏览器中超时.

我想我知道这个问题,但我不确定如何解决它.我不确定xml字符串有多大,所以我不确定声明变量的大小,所以我声明iDataBufferSize是我能做到的最大值.

以下函数有一个for循环,它创建一个返回到asp代码的xml字符串.

for循环需要经过大约500行,我认为,当它击中这条线wcscat_s(wDataBuffer,iSize,wBuffer);,它启动磁盘交换和减慢for循环.

我知道当我使iDataBufferSize更小时,它可以工作,但我担心我不会使缓冲区足够大的xml字符串.
