Re: SRB And Enclave SRB
Look at the value of SMF30SNF or SMF70NRM, divide it by 256, and that is the speedup ratio of your zIIP engine compared with the CP engine speed, and I've seen higher ratios than 4. Barry Herbert W.

Re: SRB And Enclave SRB
Hi Kenneth, The speed of a single CP on a 407 is about 210 MIPS, while the speed of a single CP on a 707 is about 1280 (per our CPU Chart). The zIIP runs like a 7xx, so yes, there is a considerable difference in CPU time between the two. We try very hard to push zIIPs (and software that offloads work to zIIPs) as one of the easiest ways to reduce the rolling 4-hour average, and often software costs. In many cases, the cost of a zIIP-enabled software product can easily be offset by the software stack savings.

There might be a strict subset documented in the pubs. - Preemptible SRBs (the class with 3 types that GA'd in 1995) all were of the "can do long-running work" variety... "preemptible" meaning that the dispatcher can pre-empt them in favor of work with higher dispatching priority. The stern "quick and dirty only" warnings around local and global SRBs were largely because they were non-preemptible... once the dispatcher gave it a CPU, it had the CPU until it relinquished control voluntarily, no preemption allowed. If you want more background on preemption Michel, look for CMG/SHARE papers from Bernie Pierce. DB2 V5 (the initial exploiter of client SRBs) used them specifically to run queries intensive enough that the optimizer chose to parallelize them (package + plan permitting, of course). - SRBs (preemptible or not) pre-date ZIIPs by years. I believe from ZIIPs day 1 they could run any preemptible work unit (SRB or task).

Re: SRB And Enclave SRB
SRB's were not meant for general application code. Also, I hope nobody builds a quick and dirty SRB routine. Those should be carefully constructed and tested. If by quick and dirty you mean short lived, then yes, that was their original use case. Some SRB routines today are much more robust and can do significant work, but that is what the z/IIP engines are for.
