Show your code. Show your measurement numbers for performance.

That isn't fair. You know what the issue is and it isn't right to try push it back on the OP to demonstrate the performance overhead of Moose.

Every time someone is surprised by the overhead of Moose in small short lived programs we seem to reply in the following sequence (where each one is admitted more grudgingly):

• It is just the startup that is slow. Moose is fine for long lived programs.
• You can use Mouse if you have to.
• Moose isn't a good fit for short lived programs.

Perhaps it would be more honest if we replied in the reverse order.
