11th Week (11.24-12.01)----PTIM test program run speed

I tested the run time of fractional operations (http://www.cnblogs.com/YangXiaomoo/p/6095583.html) using the Ptime command under DOS. The test results are generally between 0.212 and 0.217. Such as.

I then added the following code in the main function

Thread.CurrentThread (). Sleep (1000);//Suspend thread

As a result, the entire program ran for more than a second, such as.

Summarize

In the program, the artificial addition of some time delay can make the program run slowly, although this practice is back to morality, but this does give me a warning. The speed of program execution can be artificially manipulated, slowing down is easy, but to improve performance is not so simple.
