[ROOT] Speed problem for analysis macro

  I have made a macro to analyse data from a root tree. The tree contains about twenty branches using two different structures defined in a separate file and the problem is that the program is very slow and spends a lot of time to check a few entries.

  Do you know any way to increase the speed of this program? Maybe the problem is in the way I'm using the structure or in the way we read the branches.

  Thanks in advance. Best regards
