I am the QA Manager of my organization.

We have an issue which is a performance issue,

  where the process takes 6X times rather then X.

  I defined the issue as blocking since there is no workaround on

  eliminating the performance issue, and while the scenario performs badly,

  the system is busy (which is basically unaccessible).

  The product manager mentions that this issue is critical,

  and in general, performance issues will never be blockers.

  I took it to the extreme by asking:

"and what the 6x seconds were 10 hours? would it still not be a blocker?"

  and still got the same response.

Two questions:

1. Am I wrong?

2. How can I prove my point?

Thanks in advance for any advice and answer.
