The current implementation of this ticket leads to a serious performance degradation for me. While I have all freestyle projects with fingerprinting disabled, the plugin now starts to fingerprint files.

Setup: I have one specific project with 17000+ archived artifacts. These artifacts are used as a prerequisite for a number of other projects. Fingerprinting all these files adds about 15 minutes to the build time of each of these projects which is unacceptible.

Please make the fingerprinting optional, or follow the fingerprinting setting of the source and/or target projects.

Here's a suggested fix for this: https://github.com/jenkinsci/copyartifact-plugin/pull/8
It requires you to enable "Fingerprint all artifacts" on the source for the destination to fingerprint the files.

In addition, Kohsuke mentioned that he could look into reworking the digesting so that it's done during transfer. This would most likely add a negligible overhead to the copy process, and make the digest process basically free.

How long does your "Copy Artifact" process take if the fingerprinting takes 15 minutes?

Integrated in plugins_copyartifact #78
[FIXED JENKINS-12134] hide the overhead of fingerprinting into I/O.

Ringo, would you mind testing the performance of 0.21? It has something that should hopefully be a great performance improvement from 0.20, but still fingerprints. Let us know if you're still seeing unacceptable performance levels.
