In this article, we'll show you how to use Visual studio®team System development Edition or VisualStudio Team Suite to identify performance bottlenecks in your application. You will be introduced to the Visual Studio parser by walkthrough a sample performance Survey. Note that although we are using C # in this article to write code examples, most of the examples here are equall

information to the network in the form of a sequence of frames. Even the upper-level pieces of information are much larger than frames, and the link layer splits them into frames and sends them to the network. The maximum size of a data frame is called the Maximum Transmission unit (MTU). You can use network configuration tools, such as IP or ifconfig to set the MTU,for Ethernet, the maximum size is usually a byte, although some hardware support jumb

4.1Process Performance Statistics4.1.1.Kernel TimeVsUser TimeThe most basic partitioning of an application's time is the kernel time and user time. Kernel time is spent on the Linux kernel, while user time is spent on the application or library code. Linux has tools, such as time and PS, that can (roughly) indicate whether the application spends its hours on the application code or on the kernel code. 4.1.2

Introduction to performance optimization tools in Cocos development using Windows Task Manager and cocos Performance OptimizationSpeaking of the Windows platform, we soon came up with Visual Studio 2012. However, Visual Studio 2012 does not have a good tool in this regard. If we only want to know the general changes of memory, CPU, and so on before and after an e

1 IntroductionImproving the performance of your application is a time-consuming effort, but it is often not obvious what functions in the program consume most of the execution time. The GNU Compiler Toolkit provides a profiling tool for the GNU Profiler (gprof). Gprof can accurately analyze performance bottlenecks for programs on the Linux platform. Gprof accurat

" action, find the GetView () method and find that it was called 12 times, each time the CPU takes about 3MS. But every time the entire call is completed 162ms! That's a problem!The author continues to view the sub-methods of GetView () to see how long each sub-method takes in the total time. He found that the inclusive Real time of Thread.Join () occupied about 98%. He follows through, looking for the Thread.run () method of the Promoter method (which is the method that is called when creating
