Hi everybody, I'm interested in deeper informations about compression services provided by SMS.
In particular I'd like to know where find documentation on "how does it work". From my observations, compression saves disk space but it's not a "good idea" from a CPU (and it's obvious) and elapsed time (less obvious) point of view. For instance, in a simple read-compress/write-compress program (few logic), CPU consumption is really high (60% more) and Elapsed too (25% more) if compared to read-compress/write-on-tape. The normal answer could be "it depends", anyway your response will be really appreciated. Do you use compression ? What's the rule of thumb do you use ? Finally, it seems there's no zAAP/zIIP use (zOS 1.11) for such a service. Thanks in advance.
