Kees, I've just done some trial and error setup for a service unit based resource group. This one is running about 300 jobs at once.
We've noticed the behavior when submitting all these jobs after some inactivity is the work in the resource group will run unconstrained for a few minutes, and then gradually be throttled back to service unit limit specified. After approx. ten minutes the resource group cap is working perfectly. We've tested this for 8-10 hours continuous running. The service unit limit we used was arrived at through trial and error. I noticed the above behavior late in the piece. I have not checked the accuracy of the SU consumption of the resource group as we arrived at the PCTCPUBY we needed more out of luck then design, but we stopped toying with it once we got what we needed.
