Mina document NIO: NIO is an event-based Io architecture. The most basic idea is: I will notify you of events and you will do your things again, when there is no event, you can save a lot of time to do anything else. Besides, NiO's main thread is only one. Unlike the traditional model, it requires n threads, which reduces the workload of JVM and makes it more efficient for JVM to process tasks. Mina Overview • Multipurpose infrastructure for n

Google's success in the search field is undoubtedly inseparable from its Advanced Search Algorithm However, there are some little-known secrets behind it: Google's experience in running data centers is more valuable than its search algorithms. Google does not spend tens of millions or even hundreds of millions of dollars to buy expensive devices, but only millions of dollars in cheap computers to build its infrastructure. By studying hardware cost

Notes on building a high-performance web site-Infrastructure Building a high-performance web site-Application Cause It took me less than a month to finish reading this 400-page book "Building a high-performance web site". I have to say that this is the first time I have fully read a book in the real sense, although I have read many technical books. One of the reasons is that most of the technical books tend to be boring. Even if you read them
