Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.

|1||2||1||2 levels / 1 level (original posting)|
|2||3||2||3 levels / 2 levels|
|3||3||All||3 levels / all levels (all postings)|
I'd like to recommendations as to how to speed up the energy deposited being written to a ROOT file. I think I am doing this rather inefficiently now, as I define a TFile and continually write to this file at the end of every EventAction. I've attached the source and header files for comment.
The write seems to bog it down significantly. When I comment it out, I can run 10k events in a macro using a particle gun in 20seconds. When I write, it takes more like 10 minutes...
