Chapter 8 high-performance Server programming in Linux (high-performance server program framework)8. High-performance server program frameworkThe server is reconstructed into three main modules:IO processing unit. Four IO models and two efficient event processing modes.Logical unit. Two Efficient concurrency modes.Storage unit. (Not discussed for the moment)IO model:Blocking IONon-blocking IOIO multiplexing

I have been using zendframework for some time and feel it is easy to use it for development. Recently, I need to regularly execute a PHP script in Linux. After referring to the framework structure of the project, write this script (some of the business-related functions in the following script are omitted) and run it in crontab. It is normal. Write a log to write down, PHP projects do not touch every day, a

, the old and new two different frames are fitted.RTMP gives different priority levels to the data. In real-time conversations, the sound is the most important, the image is given a low priority, and the script data is given priority over the middle of the sound and the image.The RTMP protocol can create multiple data streams, but each data flow can have only one direction.With rtmp, you can build a system that allows clients to interact with the RTMP server and the application server at the sam
