分享如何使用VC的Profile工具
用VC6.0的Profile，得出结果如下：
Profile: Function timing, sorted by time
Date: Fri Jan 21 16:46:07 2000
Program Statistics
------------------
Command line at 2000 Jan 21 16:45: "E:\Projects\NewDail\Release\Dial"
Total time: 486.745 millisecond
Time outside of functions: 20.767 millisecond
Call depth: 18
Total functions: 531
Total hits: 5502
Function coverage: 32.8%
Overhead Calculated 5
Overhead Average 5
....
但显然程序执行时间远远大于486ms，另外程序中肯定执行过的一些函数，也没有被列出来，哪位大虾知道，万望不吝赐教.
另外，程序中使用了大量线程，不知是否Profile只统计主线程中的函数？

vtune is not a freeware,but you can get it from the CD of c++build4(2cd) version.In the second cd,there is a trial version of vtune4,very good!

yes, VC profile only count for the main thread,and it doesn't count the System function.
for example:
void main()
{
fucntion2();
Sleep(5000);
}
will have no difference to
void main()
{
fucntion2();
}
the sleep 5s will not appear.
So,for profile,recommand you use INtel's VTune instead of VC profile.
for example:
void main()
{
fucntion2();
Sleep(5000);
}
will have no difference to
void main()
{
fucntion2();
}
the sleep 5s will not appear.
