Example text

The output of vmstat is relatively easy to understand, and contains a large amount of useful information, divided into sections. 1. The first two columns show the number of runnable and blocked processes. 2. In the memory section, the amount of swapped and free memory is shown, followed by the memory used as buffer and as cache. 3. The swap section shows the memory swapped from and to disk. Modern server class machines should not normally experience very much swap activity. 4. The block in and block out counts (bi and bo) show the number of 512byte blocks that have been received from, and sent to a block (I/O) device.

In the system section, the number of interrupts and the number of context switches per second are displayed.

This is an area of technology that has undergone radical change and many advanced features now form important parts of the landscape. The simple mental model of a processor’s operation is now completely incorrect, and intuitive reasoning based on it is extremely liable to lead to utterly wrong conclusions. To help address this, in this chapter, we will discuss several of these advances in CPU technology. We will start with the behavior of memory, as this is by far the most important to a modern Java developer.
