I am tuning SQL query time for my slow query but every time I get different times so I can't evaluate my optimize solution.
For example, I run query
select * from abc where abc.status in (x,y,z) and abc.scale>123; three times, and I get result time like 5s, 11s, 9s.
I have turned off the query cache. How can I get a clean sandbox for tuning my slow query?
