In CentOS, we can use the top command to view cpu and memory usage in linux. Next I will give you an example to see if you need to know about it. (1) top mission The Code is as follows: Copy code $ Top-u oracle 1. top Command The Code is as follows: Copy code Top-d 1-p pid [, pid...] // set it to delay 1 s. The default value is delay 3 s. To Sort

Recently, some friends have experienced the problem of high physical memory usage of their operating system, and the most common two problems, one is that the physical memory is too low, the other is that the program occupies too much cause. So, what should we do if we're dealing with a high rate of physical memory

In this flex tutorial, we talk about some memory usage problems: the memory problem has always been a concern of programmers and also reflects the robustness of the program. for C/C ++ and other C languages, programmers should be cautious about the memory used by the program. Otherwise, it is easy to cause

Memory management of language is an important aspect of language design. It is an important factor in determining language performance. Whether the manual management of C language, or Java garbage collection, are the most important features of language. This is an example of a dynamically typed, object-oriented language memory management method in Python. object

Recently solved a problem-reducing memory usage. However, this method can only be used in WINXP and Win2k, without displaying that the main form is always running.ProgramBest. In the past, the program used 11 MB of memory. I used the dynamic window creation method to reduce the size by less than 100 kb. After applying this method, the

The memory usage of map in C ++ is studied. Many people say that erase and clear in map cannot release the memory. This statement is inaccurate after experiments over the past few days. The more accurate statement is that erase and clear in map cannot, "Release memory immediately. MAP has its own mechanism to recycle

Linux system memory usage of more than 90% -- the solution should first clarify the problem: Is the Linux system memory occupied by more than 90% of the normal range? I have a detailed explanation on the Internet, which is a normal phenomenon ~~~ The memory management method for www.2cto.com Linux/Unix systems is diffe

In the above optimization, some calculations are performed for every 500 users and the results are recorded in the disk file. These results are stored in the disk file instead of memory usage. but in fact, Python does not automatically clean up the memory. This is determined by its own implementation. For specific reas
