By introducing the matching relationship between the WSDL element and the three elements of the endpoint through the implementation chapter, we know that the binding element of the WSDL originates from the binding object of the endpoint, so how are the binding metadata and the corresponding policy assertions written to the WSDL? The WSDL Export Extension (WSDL exports Extension) and the Policy export extension (Policy export Extension) are designed for this purpose. First, WSDL Export extension

Perf profiling analysis program performancePerf profiling analysis program performance Program Performance Analysis Perf collects call stacks of a program at a certain frequency and performs statistical analysis on the call stacks. If a code path appears more ordinary in the collection result, it means that the program consumes more time on the code path. In this way, we can quickly find the code path with

The full GC is slower than the scavenge GC, so the full GC should be minimized as much as possible. The full GC may be caused by the following reasons: Dynamic changes in the domain allocation policy of the heap after the last GC System.GC () is displayed call Perm field is full Tenured was written full

This article first reviews the C Language Foundation, facilitates the subsequent code reading. 1 About elf FilesThe target files and executables that are compiled by C in Linux are in elf format, and the executable file is divided by segment, in the

, there is not enough memory space for its use, there is an out-of-memory; for example, an integer is applied, but a long can be stored to save it.memory leak memories leak, refers to the program after the application of memory, can not release the requested memory space, a memory leak damage may be ignored, but the memory leak accumulation of serious consequences, no matter how much memory, sooner or later will be occupied. In fact, it is not recycled after the memory space has been used. Other

In the process of developing Java programs, it is unavoidable to encounter problems such as memory usage, performance bottleneck and so on. The Java Profiler Tool helps developers locate these issues quickly and efficiently, making it an important tool in the Java development process. At present, there are a variety of Java Profiler tools in the market, this article will briefly introduce several kinds of tools that are common at present, and compare them from the aspects of function and perform

Introduction: Tuning is not always speed, sometimes need to adjust other aspects of the application, if the application needs tuning, the first thing to do is to use the profiler to monitor the application. However, profiling is not always feasible, and sometimes the reason may be ridiculous. In this installment of performance, Jack and Kirk talk about one of their recent experiences: they were instructed to dissect a fat client, which was actually so

C compiler profiling _ 5.2.3 intermediate code generation and optimization _ access array elements and struct members through "offset" Section 5.2.3 accesses array elements and struct members through "offset" In the previous section, we introduced the access to "array elements and struct members". We use the "base address + offset" mode to calculate the address of the memory unit. For the array element arr2 [I] [2], the array index value I is a variab

C compiler profiling-managing the register for generating assembly code In a computer, the CPU speed is much faster than the memory speed. The compiler should make full use of register resources to reduce unnecessary access to the memory, this increases the speed of the compilation code generated by the compiler. In the intermediate code generation stage, the UCC compiler uses the temporary variable t to store the values of common subexpressions such

string "charger" to save it to the Is_charger variable, is_charger non 0 indicates that the previous android was started in charge mode, otherwise normal mode. The normal startup mode is different from the process that the charging mode needs to start, and the difference between the two modes to start the specific program will be described in init.rc parsing.Next, call the info macro to print a log statement, which is defined in Init/log.h and is implemented as follows#define ERROR (x ...)
