Dear experts,
When merging several root files using “hadd” I noticed something which seemed a bit odd to me, namely the size of the merged file being more than twice as large as the sum of the sizes of all its constituent files. The command I used is basically:
“hadd merged.root someDirectory/*root”
and in my case the sum of the sizes of all root files in the directory I want to merge is 9 GB, and the merged file has a size of 22GB. Is this behavior normal or does it mean I am somehow doing something wrong?
Thanks for the help!
regards,
Willem
