Original in: http://rdc.taobao.com/blog/cs? P = 1062 Many TCP adjustment parameters are introduced here, which is very exciting. For a server, we generally consider the QPS that it can support, but for an application, we need to focus on the number

Concurrent programmingMemory barrier (RAM fence)CPU Level1.CPU has a number of pipeline, executing code, will execute code in parallel, so the CPU needs to assign the program instructions to each pipeline to execute separately, this is disorderly

10th Chapter System Level I/OI/O: the process of copying data between main memory and external devices.10.1Unix I/OA UNIX file is a sequence of M bytes:B0,b1,b2 ... Bk... B (m-1)1. All inputs and outputs can be executed in a uniform and consistent

Even senior technicians, I often hear them talk about how certain operations are causing a CPU cache to refresh. It seems that this is a common misconception about how the CPU cache works and how the cache subsystem interacts with the execution core.

HTTP persistent connection 2 million attempt and Optimization For a server, we generally consider the QPS supported by the server.(Querypersecond ))But there is such an application, we need to focus on the number of connections that it can support,

For a server, we generally consider the QPS that he can support, but there is an application where we need to focus on the number of connections it can support, not the QPS, and of course the QPS is one of the performance points we need to consider.

Summary of Android data persistence tools Programmers are the lazy creature and never duplicate the wheel during development. In actual development, data eating is a problem that must be solved, I will summarize several tool classes in addition to

Java NIO Study Notes The project team is engaged in IM products, and the server certainly uses NIO technology as the communication bottom layer. However, I have always been familiar with some NIO theories and have no practice. Now I am free to

How do you usually read the files? Use stream read. Yes, C # provides us with a very powerful class library (once again touted.) NET, which encapsulates almost everything we can think of and we do not think of class, stream is the general means of
