Andrew, I think you should go with 16. I know that a quad core is not the same thing as 4 CPU's..BUT.it is for most practical purposes.I believe the terms core and cpu are used loosely to mean the same thing these days when referring to CPU power..it's my understanding that to make a quad core cpu, they shrunk the technology of a single core to be able to fit 4 dies on the same chip..so while you are more constrained on bus because you are all on one chip.your processing power should be better than a single core on a single cpu..
I know I'm going to get a lot of flack for my loose and probably improper usage of terms..but that's roughly how I think of it J From: Action Request System discussion list(ARSList) [mailto:[email protected]] On Behalf Of Goodall, Andrew C Sent: Thursday, March 22, 2012 5:57 PM To: [email protected] Subject: fast and list threads - by cores or cpus? - documentation conflicts. ** I'm confused - the doc seems to conflict and BMC architects have signed off on our ar.cfg settings in the past in which they were set by CPU and not by Cores. My previous understanding was that these values should be set by the number of CPUs and not Cores, in fact BMC architects have signed off on these settings many times - and if you look at "BMC Remedy AR System Server 7.6 - Performance Tuning" page 33 - it states CPUs However, in the recent publication for performance and scalability "Performance and Scalability White Paper" released this month - see page 4 and 48 - this was set at the number of total cores. So - we have a Quad CPU 2.2 GHz Quad Core AMD with 12GB ram Windows box. So should I use x4 or x16 = a huge difference in the number of threads, which could substantially impact performance.
