Re: Interesting Marketing

It's been on my website for 3 or 4 years -

create table kill_cpu (n, primary key(n)) organization index
as
select rownum n
from all_objects
where rownum <= 23
;

select count(*) X
from kill_cpu
connect by n > prior n
start with n = 1
;

Under Oracle 9 you have to enable the
old connect by, but under Oracle 8
this will do 4M CR Gets and 6M
'buffer is pinned' visits.

Time it on your CPU, and compare it
with a disc doing a nominal 100 random
reads per second.

Typical (ballpark) rate is 10,000 LIO/s
per second per 100MHz of CPU.
