What does the next piece of code output?
I interviewed a lot of people for this problem and most of them said that the date was the output. But the real result is undefined. Why is that so? This leads to a conceptual--hoisting, in
are always some CPU threads waiting for the CPU VP and should increase the number of CPU VP.
Command Onstat-glo can display information about the CPU VP.
From the system point of view should be monitored at any time to analyze the CPU usage, to understand whether the system has the potential to dig. There are many systems that provide this type of tool, such as SAR. As long as there is CPU idle time or i/0 wait time, it is possible to increase the
