python memory usage

Usage of with as in python, and usage of python What is the With statement? Some tasks may need to be configured in advance and cleaned up afterwards. In this scenario, the with statement of Python provides a very convenient processing method. A good example is File Processi

disconnected from all the processes that accessed it, the IPC_RMID subcommand is immediately removed, and the shared memory identifier is removed and the shared memory area is deleted, along with any associated data structures;If there is still another process remaining connected to the shared memory, after calling the IPC_RMID subcommand, the shared

records are obtained. As you can see, a large number of temporary variables are created in the middle, which leads to a sharp increase in memory. After a large number of temporary objects are created, they will be recycled immediately. GC is under great pressure. In the design document, only 10 records that match the most are required to be returned, which does not seem to be noticed in the previous solution. After taking over the service, the first

* Note: During the optimization of the system over the past few days, it was found that the entire software took up MB of physical memory as soon as it was started, and it was a little hard on the HP Workstation, let alone on a normal PC. However, I found that the physical memory usage was only about 10 MB after the software was minimized, so I felt that there wa

0x26010002. To query the node number of a file index, use LS-I. However, after the reconstruction file is deleted, the index node number is allocated by the operating system according to the usage of the current file system. Therefore, the index node number obtained is different from the original one. Based on the file (or directory) name specified by pathname and the number specified by the proj_id parameter, the ftok function generates a unique key
