Try setting MAXDOP to 1-8 on your test server instance and see if that changes things.
Also run some typical queries that are behind some of the slowest actions on each platform (in SSMS on the server).
Compare time, IO and query plan. This way you are taking the app out of the equation
Is anything else running on the PROD server. What does cache hit ratio and page life expectancy look like?

Also, check the power saving settings on the PROD server.

Society has varying and conflicting interests; what is called objectivity is the disguise of one of these interests - that of neutrality. But neutrality is a fiction in an unneutral world. There are victims, there are executioners, and there are bystanders... and the 'objectivity' of the bystander calls for inaction while other heads fall.
