Disk IO and CPU in sp_who2


hi,

please tell me in case disk io more cpu time , vice-versa --cpu time more disk io

and if disk io cpu disk io --377889  , cpu --89

and disk io more cpu cause problem in database...

thanks

disk i/o , cpu time independent metrics.  session can have large amount of disk i/o little cpu time , visa versa.  1 can't ascertain whether values abnormal since values cummulative since session established.  numbers reported sp_who2 provide quick high-level overview of session activity , not particularly useful in performance monitoring.
