I think the answer to the standard STORBUF: Q1=125% Q2=105% Q3=95% not causing me grief is that I run production in Q0 due to quick dispatch being set. Production on averages owns 25-30 percent of real pages and never goes below 15 percent, so it is really hard for Q3 machines to get up

Why overkill? It is the setup that is decided on. Give production an absolute priority above everybody else, and let the rest contend in a free-for-all. Besides, if production does go long dormant it will lose it real pages. When it becomes active again we don't want it to be held back by

Re: swap to DCSS documentation/cookbook?

With DCSS, will it be first fit, or moving cursor allocation? First fit is optimal, vdisk is moving cursor. DCSS should be paged out with the same rules as vdisk, but this needs to be verified in real life. The CPU savings are obvious, but are we talking 1 percent of 1 percent of an IFL?
