I have been testing this extensively over the last few months. I do a
full table scan with a db_file_multiblock_read_count =3D 1 and then one =
=3D
128( i check the 10046 trace to verify i am getting this much) and I see
absolutely no difference whatsoever in response time.=20
i am doing=20
select count(*)
from heap_table;
I have tested this on windows xp, solaris, with EMC, netapp, and regular
old cheap off the shelf hard drives. I have tested it in 8.1.7,
9.0,9.1,9.2.
has anyone see a response time improvement from this parameter anywhere?
