Users may sometimes experience a situation where the CPU for the system process is nearly 100% long. The traditional way to analyze this problem is to add CPU counters for all the threads in the system to the Performance Monitor, then find the highest CPU thread, and then parse the thread's memory address with the process Viewer and the PStat tool. In order to id

The method for obtaining the CPU usage in Windows NT/2000 is different from that in Windows 9X. The "performance counter" is not used for obtaining the CPU usage in Windows NT/2000 ". Instead, it uses ntquerysysteminformation, an API function not publicly available in Ntdll. dll. For more information about its

You want to know the CPU usage during Java programming so that you can decide whether to load the task. First with Google search, Windows environment can use JNI through the API function Getprocesscputime () to get, and someone gave the source code. Linux seems to have no one to give the source code, so decided to write one, after practice, and finally succeeded, is to post code, and share with you.Thinking

Elapsedticks property is obtained. But in general the error is not very large. It is recommended to use the elapsed and Elapsedmilliseconds properties if the exact calculation time is required or if the amount of test data is particularly large.There are questions :After my test, I found that I had not answered the original author, as I have said. The friend who wants to know the reason is indicated below. Thank you.From an internal implementation, Stopwatch.ishighresolution = True, StopWatch.E

properties, as follows:private Listprivate ListThese two properties W will be used, the reason is that the above mentioned warning, because I first released the O service, O Service set the two properties, and the W service has not been published, so that hession in deserialization, the detection of Propertyao does not exist, So the warning is given. But does this have anything to do with the high CPU?Having discussed it with colleagues, he mentioned

In one of my Asp.net sites, the and B functions are provided, both of which consume Web Server resources (mainly CPU, it takes about half a minute to complete the function. If one user is using one of the and B functions, the CPU usage of w3wp is about 50%. If two or more users use one of the and B functions at the same time, the web server will become overwhelme

solving CPU usage began with the idea of "can reduce the cycle precision. It is known that, under normal circumstances, executing Sleep (1) will Sleep for about 1/50 seconds. This time is not accurate or accurate, and it does not seem to be able to meet the smoothness requirement of 60 fps. However, if the frame speed of a game does not need to be so high, such as 30 fps ?? This solution is very feasible.
