You are measuring the I/O savings provided by storage indexes for Table A.
One of your scripts displays the I/O savings as a result of the storage indexes. Which two statements are true?
SQL> select count (*) from transmap.mymap_comp
2 where map_id between 400 and 500;
COUNT(*)
103000
Elapsed: 00:00:00.08
SQL> select b.name, a.value/1024/1024 value
from vSmystat a, vSstatname b,
where b.statistic# = a.statistic#
and b.nafne in (cell physical IO bytes eligible for predicate offload',
cell physical IO interconnect bytes',
cell physical IO bytes saved by storage index',
cell physical IO interconnect bytes returned by smart scan') order by 1;
Statistic Value (MB)
cell physical IO bytes eligible for predicate offload 2,255 .09
cell physical IO bytes saved by storage index .00
cell physical IO interconnect bytes 1.72
cell physical IO interconnect bytes returned by smart scan 1.68
