Troubleshooting of insufficient system memory caused by excessive memory usage by Linux Server CacheProblem description When the memory usage of the Linux Server exceeds the threshold,

Different businesses have different designs, but at least they all share common pursuits, such as performance. I have been developing servers for many years. Sometimes I am asked what is the server performance? What is the competition between various servers? The simple answer is QPS and concurrency, but sometimes it may be wrong to think about it. QPS and concurrency are for the same service. Different services may cause different pressure on the sam

Detailed design of data serverData server is designed with three levels of data synchronization, to achieve high-speed player data acquisition and modification.Data levels are divided into: memory data,Redis data,mysql dataDesign Purpose: First of all to ensure the reliability of data, to

ratio of the system to use the cache (for Windows 98) on the "main use of computers" tab ). If the system has a large amount of memory, you can select "network server". In this way, the system uses a large amount of memory as the cache. In the CD-ROM label, you can directly adjust how much

We are concerned about how to optimize memory management, improve memory usage efficiency, and increase the running speed as much as possible. The following describes how to improve memory usage and optimize memory management in

linear structure, and the heap is a chain structure. Each thread of the process has a private "stack", so each thread, though the code, is not interfering with the data of the local variable. A stack can be described by "base address" and "stack Top" addresses. Global variables and static variables are allocated in the static data area, and local variables are allocated in the Dynamic Data area, which is the stack. The program accesses local variable

Recently discovered that Svhost always consumes a lot of resources (memory, CPU) when it is powered on. After some Baidu, take its essence to its dross, a simple summary of the general how to solve the problem: Open Task Manager and find the PID of the resource-intensive svhost process, assuming it is 123 Run cmd (Windows function key +r, enter CMD and r

Process, thread, and memory management are the most basic services of the kernel and the main components of the kernel. These aspects are the basic knowledge that a software developer must possess. Although a person does not understand this knowledge, he can also write simple Program But such a program can only be regarded as a fur. With the knowledge of processes, threads, and

The way that shared memory works is to map a physical memory to the respective virtual address space of different processes so that each process can read the same data to enable process communication. It is the most efficient method of data exchange because it is used for communication through

Background: Performance monitoring shows that the CPU usage of a single core of the online server has reached 100%, which is caused by one of our core services. Thanks to the fact that our service processes are undertaken by multiple identical worker (thread) scheduling tasks, in addition to the high CPU
