We would need more info on where your people think it is slow at.
Personally, the only performance hits I have noticed is a hit at start 
up (everyone knows that), and using native delegation using 'exists' on 
hashes.
As a test, checking a list of 75k key values against a large hash took 
less than a second using a native hash. Using moose with a hashref and a 
handle to 'exists' took about 34 seconds. That might be an issue, but 
the fix is easy, just don't use a handle and make your own method.
