Parallelizing with 2 processes.

hadd compression setting for all output: 101
Each process should handle at least 3 files for efficiency. Setting the number of processes to: 2

I thought using the -ff option would solve this.
Also checking the compression settings of the inputs, they seem to be 101, just like the target compression settings here.
I used a different ROOT version to create the inputs, that said. Could the issue be coming from that ?
