DB2 Explain Plan takes forever

Last Modified: 2020-03-01
DB2 10.5 on Windows Server 2012

I can have a query that takes 3 seconds to run and then when I look at the explain plan, it takes 2-5 minutes to generate.  And it seems to be getting slower.  

How can I speed this up?  In my QA environment the same operation takes like 20 seconds to generate.
