Considering all the discussion here, I'd like to ask a question and make a statement for those a little more familiar with server architecture
I have a year old Sun Fire x4200 server, two Dual Core Opteron 275s, which performed much better with UV and in general than my brand spankin' new Dell PowerEdge 1950, with two Xeon Woodcrests (Core 2 Duo-based). Each machine has 16G RAM and similar hard drive configurations. Both run Windows Server 2003 x64 Standard Edition R2 Service Pack 2 and UV 10.2. Get this-- The new Dell benchmarked lower and does something very strange. On the Dell, the System process (not System Idle Process) often jumps between 3 and 20 percent, all the time. My suspicion is that AMD Opteron based multiprocessor (meaning multiple physical processors) perform better because they can transfer data between physical processors and associated DIMM slots across the hyper-fast HyperTransport bus, and not the slower (in the Dell's case, I believe ~700 MHz) system bus on Intel-based machines. Because the Sun machine is faster we are moving our production UV system back to it this weekend. Anyone want to confirm this for me? Or does anyone know how I can track down what the "System" process is actually -doing-? Just my experience, thanks-- Gabe ------- u2-users mailing list [email protected] To unsubscribe please visit http://listserver.u2ug.org/
