Hi John, Your comment is wise: Just because you can do something doesn't mean it's worth doing. This is a great summary of our quest to zIIP enable a bit of our COBOL code. Of course, this also means you have to do your homework because it may just turn out that, in some cases, it's *definitely* worth it. A System z ISV in this day and age can't afford to miss those cases (at least that's my philosophy).
For example, zIIP enabling our core HostBridge products, "Base" and "JSE" (our CICS-based JavaScript Engine), was a no-brainer Likewise with HB Socket Support (zIIP-enabled EZASOKET alternative). On the other hand, our COBOL/BMS utility transactions??? Not so much. I must add that this "break-even" assessment is a moving target because zOS processor switching overhead seems to be trending down (and our own code paths are getting shorter). Note also that the model of the System z hardware makes a big difference. If the GPs are knee-capped relative to the zIIPs, the GP savings and potential improvement in throughput are staggering in some cases.
