disk reads and IO wait time vs spatial request

Hi,

I'm new in this community.  Working with Oracle Spatial since a couple of weeks only. 

My question concerns the "disk reads" and "io wait time" performance figures in oracle performance tables. 

I have a situation in which IO wait time / disk reads gives a very unefficient result for requests using spatial domain indexes.  In my case 0.05 sec per disk read.  

The spatial index is on the same file system than other standard index and when those spatial indexes are not used i get 0.0005 sec per disk read which is a lot better and quite normal considering the type of storage we are using.

Howdy, Stranger!
