Restore/Duplicate takes a lot longer to restore than backup

We are doing a compressed backup of a 200G database in about 2 hours. When we
run the duplicate command, we copy the production backup files to the local
disks of the target server. We then run the RMAN duplicate command and it
takes over 6 hours. Is it reasonable that a restore/duplicate from a
compressed backup takes that much longer than the actual backup? Is there
anything that can be done to speed up the process?
