Ken,  

There is no direct correlation. The values that I have seen from many customers are in the range between 1,000 and 1,600.

I have a system that when system stats are gathered (using either no workload or with a workload) show a value of about 1260 for cpuspeed/cpuspeednw. The server is IBM p7 with 3.5ghtz cpu's. I expected the values returned by oracle to be close to 3500. Is my assumption incorrect? Is there a direct correlation between actual clock speeds and the value reported by the database? DB version is 11.2.0.3.

Thank you in advance,

Ken
