Course Introduction:Have you ever encountered various memory problems in Linux systems? Such as memory leaks, memory fragmentation, etc. These problems can be solved by in-depth understanding of Linux kernel memory fragmentation prevention technology. The way the Linux kernel organizes and manages physical memory is the buddysystem, and physical memory fragmentation is one of the weaknesses of the buddysystem. In order to prevent and solve the fragmentation problem, the kernel has adopted some practical technologies. These technologies will be summarized here. 1. When the memory is low, the fragments are integrated to apply for memory pages from the buddy. If a suitable page cannot be found, a two-step process of adjusting the memory is performed, compact and reclaim.

Course Introduction:How to solve the memory fragmentation problem in C++ development. In C++ development, the memory fragmentation problem is a common and troublesome problem. Memory fragmentation refers to the situation where allocated memory blocks are disconnected during use, resulting in less allocable continuous memory space, thus affecting the performance and stability of the program. This article will introduce some common methods and techniques to solve the memory fragmentation problem in C++ development. 1. Reduce the number of dynamic memory allocations. Dynamic memory allocation is one of the common causes of memory fragmentation. In order to reduce the number of dynamic memory allocations, you can

Course Introduction:In C++ programming, memory management is a critical skill. Properly managing memory can improve program performance and stability. However, if not handled with care, memory fragmentation and memory leak issues can have serious consequences for your program. This article will introduce some advanced C++ memory management techniques to help developers avoid these problems. Memory fragmentation refers to small unused chunks of memory scattered across the heap. When memory is allocated and released frequently, a large number of memory fragments will be generated, resulting in memory discontinuity and waste. A memory leak refers to the application

Course Introduction:Optimizing C++ memory allocation strategy is crucial, including choosing the appropriate allocator (new/delete, std::allocator, third-party allocator) and allocation strategy (heap allocation, stack allocation, object pool, slab allocator). Through optimization strategies, memory fragmentation can be reduced, program execution speed can be improved, and memory leaks can be avoided. In practice, object pools can effectively optimize the allocation of large numbers of objects. For example, preallocating MyClass objects can reduce fragmentation and overhead.
