I have a strange problem with storing TLorentzVectors.
I have a root file with px,py,pz,pt and some more information about tracks on reco and truth level.
I tried to store the reco tracks in TLorentzVectors and save them to a new root file for a better handling.
A sample input file is 9.9MB while the output (with the TLorentzVectors only) has 11MB even after discarding all truth information…
Any idea why the needed disc space raises that much? Any chance to avoid that?
