Hi, Sorry if I missed the point; here is a short description of what I want to do I have a program for medical image reconstruction that needs to write lots of histograms and profiles to disk for further analysis. Currently this program uses PAW. Since the data analysis with PAW is not a trivial task for people at clinical sites, we want to change the program to use root and provide an analysis tool. Within this program (the image reconstruction) I observed a significant slowdown of all routines even those, that are not related to root. The example I provided, just showed, that even such simple pieces of code are influenced by root. Now to my question: how can cope with the slowdown that occurs whenever I link against the root libs? Thanks in advance Thomas Nisius >Hello Thomas, > Could you elaborate what was the in initial cause of your investigation? > For example for sure ROOT needs some time to be initialized since it loads dozen the share >libraries (DLL’s). > To get the right answer one should ask the right question.
