How big are these artifacts? At /threadDump, you can access live stack traces. Maybe look for something fingerprint related during those 5 minutes, it could give you a hint what is taking so long.
Copy artifact works without fingerprinting in the source project, but always calculates its own when copying. See JENKINS-12134 and JENKINS-18653.
