The example of Coroutines in java by using https://github.com/offbynull/coroutines

The example of Coroutines in java was using coroutines

You can use this example to compare the performance between the tradinational thread model with coroutines model.

Step 1

mvn clean install

Step 2

Examples  

java -jar target\coroutine-model-jar-with-dependencies.jar   

Usage: java -jar jarfile [args...]    
       (to execute a jar file)    
where args include:    
         first : simulator task count, default is 1000    
        second : io waiting time for each task, default is 10ms    
         third : max thread to handle the task when using thread model, default is 200    
                 coroutine model will ignore this parameter    
Examples:    
          java -jar thread-model-jar-with-dependencies.jar 1000 10 200    
          java -jar coroutine-model-jar-with-dependencies.jar 1000 10    

Here is performance report

From the result showed, we can have a clear answer, if there are existing huge thread in your application and many of them are blocked. In this scenario coroutine model have much better performance than the traditional thread model.
