Hi Melvin

As an answer to a previous post you wrote:

"Also, your main problem is that when you have two exact same queries executing at the same time, they will cause
contentionin
 
the disk, and neither one will make much progress."

Could you elaborate a little more on the meaning of "contention in the disk"?
What is it that happens?

Thank you and have a good day.
Regards
Charles
