Dear ROOTers, I was using ROOT version 3.01/06 for some time. Using h2root, I converted a 50K event ntuple made with ATLFAST into a .root file. I used the TTree::MakeCode() method on the root file and created my script which took about 30 seconds to run with version 3.01/06. I downloaded and installed the binary version 3.02/07. That exact same script now took 10 minutes to run! Another side effect (related, perhaps) is that a segmentation fault occurs when I run this script for the first time after starting ROOT. The segmentation fault is non-fatal and the interpreter recovers. I can't figure out where the speed is lost and why the segmentation fault occurs. Maybe it's a backwards non-compatability? Any idea would be appreciated. I'm back using 3.01/06 for now.
