Subj:   Re: Parallel Efficiency
 
From:   Bakthavachalam, Roopalini

Hi Dave,

The below query gives me CPU EFF as 2.98% and LogicalDevice Eff as 8.58%. Does that mean that my Teradata system has very poor efficiency at this time.

     SELECT

        (AVG(CPUBUSY)*100)/NULLIFZERO(MAX(CPUBUSY))
            (FORMAT 'ZZ9', TITLE 'CPU//EFF//  %'),

        AVG(LogicalDeviceIO)*100 / NULLIFZERO(MAX(LogicalDeviceIO))
            (FORMAT 'ZZ9', TITLE 'LDV//EFF//  %')

        FROM DBC.RESGENERALINFOVIEW

Could you help me understand the results I have got?


Thanks

Roopalini
