Build

In a machine with ROOT setup do:

make

to get test

Run

./test 100000 1

will:

1. Create two files file_1.root and file_2.root.
2. Load them, add a branch with RDataFrame
3. Save them.
4. Load them again.
5. Merge them and save the merged file.

./test 100000 2

will:

1. Create two files file_1.root and file_2.root.
2. Load them in a chain.
3. Clone the chain.
4. Add a branch.
5. Loop over the chain adding entries to clone.
6. Save.

Both methods will be timed. Results in my machine:
