We have a project that creates a 3.2 GB file that needs to be archived. We are currently running Jenkins 1.417. The building of the project works just fine but when the archival step begins the process takes forever. I allowed the job to run for more than 12 hours and the archive never completed.

I can manually copy the files in a fraction of the time (only a few minutes for a build directory of over 15 GB). Increasing the amount of memory available to Jenkins does not improve the copy performance. While the files are being archived the java process takes 100% of the processor cycles on a single processor core. Memory usage does not increase significantly regardless of the number or size of the files to be archived. And disk utilization during the archival process is unbelievably low as well.
