Linux shared memory practices (1) and linux shared memory practicesBasic concepts of shared memory The shared memory zone is the fastest IPC format. Once such memory is mapped to the address space of the process that shares it, data transmission between these processes no lo

1. Basic ConceptsMemory overflow: Simply said memory overflow means that the program is running in the process of requesting more memory than the system can provide memory, resulting in the inability to request enough memory , and then a memory overflow occurred.Memory leaks

Linux inter-process communication (IPC) programming practices (8) use of shared memory-POSIX shared memory (API) 1. Posix provides two methods to share memory areas between unrelated processes: (1) memory ing file: open the function first, and then call the mmap function to map the obtained descriptor to a file in the

In Android apps, the most memory-intensive is the picture resource. And on Android, when reading bitmap bitmap, the stack size of the pictures in the virtual machine is only 8M, and if exceeded, a outofmemory exception occurs. Therefore, the memory optimization of the image is an important part of Android application development.1) to recover bitmap memory in tim

Today, someone told me that the memory on the Linux server is not fast enough, 128G of memory, will be used up immediately. I was startled, the application on this server is now very small, ah, how the utilization will be very high. First use Zabbix to see the next, memory remaining space is still very big, there is 117G of spare ah. Then log on to the server aga

　　In the previous article introduced several multi-channel programming memory management mode, the Exchange memory management is most flexible and advanced. But there are a lot of major problems with this strategy, and the two most important issues are space waste and program size constraints. So what's the solution to the problem of swapping memory? The answer i

Java Memory Allocation and Management Summary and java memory allocation Summary I want to write this summary for a month, but I still feel that I have almost nothing to write. I 've been fighting for the last two days. I decided to write out the materials and notes I checked earlier. If you are familiar with answering a few questions, please let me know.
