In particular under AIX, you gain a huge amount of compilation time. For the "memory leak" problem, do you get the same problem if you run only a few events, if yes, could you send me the ouput of TTree::Print immedialy before file->Write(). Could you also check that when you create the Tree, you indeed have a TFile object as the current directory? Otherwise root will try to create this Tree in memory and it may take a lot of memory to save it as one single object to a file. Rene Brun
