Subj:   Re: CPU vs Disk IO
From:   Martin O Brien

Hi Craig,

The rule of thumb that I use is around (500 - 1000) to 1. The reason why the ratio is much lower could be due to highly cpu intensive tasks such as

- duplicate primary index checking (NUPI duplicates)

- product joins (perhaps due to lack of statistics or stale statistics )
