In practice the second pass is often done in cache: Size data is not very big so you have to have a small cache for it not to fit.

comment correct xargs parallel usage
You are most likely hit by I/O: The system cannot read the files fast enough. Try starting more than 40: This way it will be fine if some of the processes have to wait for I/O.

comment How to copy files from other servers if local machine is down
A way of testing it without taking the machine down is to add a null route: sudo route add -host remote-server gw non-existing.ip.on.local.net e.g. sudo route add -host 130.228.1.10 gw 192.168.1.248

If your cluster has more than one machine (e.g. 4 machines with 8 cores) use '-S server1,server2,server3,server4'.
