The startup time for servers increased during the last years. So even for development and test servers it’s now common to either let them run or pause them. On z/VM with Linux on System z there are two different methods to accomplish that:
- the basic Linux suspend / resume feature
- CP STOP and BEGIN mechanism
There is now a new publication looking at this in more detail, especially focused on overall performance. The paper is available on Infocenter in HTML and as PDF.
