OK, I have a look to the links and still thinks that I don´t underestand quite well, I explain to you :
After lloking in the CPU´s in OS I can see that the threads are spread in all CPU´s look attachment ( CPU.jpg ). After this I tried to check the JVM working mode and I go to jconsole, and now in this case I am not able to get more than 25% of CPU, look the graph... (jconsole.jpg) Do you have any idea why the JVM of the jmeter is not able to go further than 25% ?
