Is parallel a great idea here? If dir1 and dir2 local to a single file system then parallel will not speed anything up, if anything it will slow it down causing lots of context switches waiting on IO, you can just take out the z option too as that will be gaining you nothing and wasting a fair amount of CPU time. If it's a remote directory you kind of have the same problem as your network will be the bottle neck this time, but parallel could really speed up the compression/decompression step for this at each end.
