What are you driving at? IBM is delibately crippling the Oracle result? Somehow I doubt it. I'm guessing its just a case of DB2 being more optimized and therefore faster for the AIX/Power5 system. As for more clients/spindle .. well if the system can handle it, they would need more clients/spindles. Adding more spindles/clients to a system already running at near 100% CPU load would not get you a higher TPC-C result. Received on Sat Jan 22 2005 - 18:14:45 CST
