Over the last few months a problem has grown with my contacts when using my MacBook Pro.  When I click the Contacts tab, then attempt to click a contact or initiate a search, I get the pinwheel for 30+ seconds before I can interact with any contacts.  This happens every singe time I return to the Contacts section.

I have a second Mac where I'm also using Outlook to access the same Exchange account.  This problem does NOT happen on the MacBook Air.  Same Exchange account in both cases, same version of Outlook (14.3.6).

I created a new identity today and let it rebuild the data directly from Exchange.  I'm experiencing the same thing with the rebuilt identity.

Where should I go from here?
