BTW if you need some numbers to compare, here is a link to SQL.ru thread on this topic with CPUSPEED/CPUSEEDNW data for some CPUs/Oracle versions: http://www.sql.ru/forum/actualthread.aspx?tid=682014&pg=5&mid=10015821#10015821 Regards

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