docker memory usage

The PHP built-in function memory_get_usage () returns the amount of memory currently allocated to the PHP script in bytes (byte). In the actual development of the web, these functions are very useful, and we can use it to debug PHP code performance.The Memory_get_usage () function returns memory usage, the Memory_get_peak_usage () function returns the peak

I Came authentication SS some questions about how to evaluate the memory usage of a process. it seems to be an easy task since most operating systems have provided a set of powerful tools to investigate memory usage. but what confuses the users is the power and complexity of these tools. and different tools may use dif

How to optimize memory usage memory optimization principleTo optimize the use of memory for applications, developers should first know what consumes the most memory, and the answer is texture! Textures will almost occupy 90% of the application

When the number of concurrent TCP connections for a server is timed at 100,000, we are interested in how much memory a TCP connection consumes on the operating system kernel. The socket programming method provides interfaces such as SO_SNDBUF, SO_RCVBUF to set the read/write cache for the connection, and Linux also provides the following system-level configuration to set up the TCP memory

This paper gives a general analysis of the application scenarios and characteristics of Redis, and makes a detailed analysis of the usage scenarios of the common data types of the APSARADB and the aspects of memory optimization and performance optimization. Redis Common data typesThe most commonly used data types of Redis are the following five kinds: String Hash List Set Sorted Set

The Java. Lang. runtime class provides the java. Lang. runtime class to view the current JVM memory usage. Each Java instance (Virtual Machine instance) has only one runtime instance. You can use runtime. getruntime () to obtain the runtime Instance Object of the current virtual machine. Runtime provides three methods to obtain the maximum memory available for th

A lack of physical memory affects both the performance of Linux desktop systems and server systems. The first thing to do when your computer slows down is to free up memory. In particular, in a multiuser environment and in a mission-critical server environment, memory consumption becomes more critical because multiple users and application threads compete for mor
