High-performance TCP UDP Communication Framework HP-Socket v3.2.2 officially released, tcp HP-Socket is a set of common high-performance TCP/UDP Communication frameworks, including server components, client components, and Agent components. It is widely used in TCP/UDP communication systems in various application scen

is the Key-value type database, is directly in the memory carries on the access data, therefore has the very high performance. The use of Redis can reduce the pressure on the MySQL server and reduce the number of communications with the database server. The bottleneck of the second kill is the speed of communication with the database server (MySQL itself's primary key query is very fast) 2.2 Configure Redi

this is to write high performance code in the best practice for the first time, rather than writing a bunch of garbage code and then thinking about optimization. Believe that after the work everyone will be after the optimization of the cumbersome are deeply experienced. Once you decide to write high-performance Lua

application System is basically independent of the database, if you have coupled the database JDBC-driven configuration in your Java application system, Then your Java EE application system has a database concept color, as a mature need to promote the Java application system, not recommended and specific database coupling, of course, how to ensure that the

A few days ago, I received the book "High-Performance JavaScript" from HTML5 China and intended to take it as a holiday pastime and write an article documenting some of the key points in the book.Personally think this book is worth the low-level other front-end friends to read, there will be many unexpected gains.Chapter I load and executeBased on the logic of the UI single thread, the loading of a regular

, Web developers can set up multiple filters, each filter can be loaded with multiple filter classes. By reading the configuration file information, wrapper loads the filter sequentially and passes the request. The service method of the servlet is invoked at the end of the filter.?Standardwrapper needs to hide most of its public methods from the servlet programmer. Therefore, the Standardwrapper class wraps itself as an instance of the façade class Standardwrapperfacade. Façade design patterns a

screen tearing, that is, the top half is the previous picture, the lower half is the next picture: In the JavaScript high-performance animation and page rendering of this article, for example, in 14ms, then only the number of frames added up to more than 16.7ms, then will certainly drop the frame, and each frame delay time is 2.7ms, so 16.7/2.7= 6 that is, in the sixth frame will definitely drop frames!!

Analysis of High-performance I/O models Analysis of High-performance IO Models High-performance I/O models are often required for Server programming. There are four common I/O models: (1) Synchronous Blocking I/O (Blocking IO):

Summary of Performance Optimization for 35 Java codes and java Performance Optimization Preface Code optimization is a very important topic. Some people may think it is useless. In some small places, what are the effects of modifying or not modifying the code on the code running efficiency? I think so. Is it useful t

supported, but the indexes are read-only.MySQL built-in other storage engine Archive: Suitable for high speed insertion , quick insert. blackhole: There is no storage mechanism, he discards all inserted data, but the server logs the table log, so it can be used to copy the data to the repository, or simply to log. CSV: You can process a normal CSV file as a MySQL table, which does not support indexing. The CSV engine can copy or copy
