dynamical versus non dynamical for TH1F

Hello,

i'm using a basic root program (.C) that allows to make some histograms of variables of a given ntuple (a .root file)

Up to now, i created the histogram dynamically with TH1F *myhisto=new TH1F(...)

i was wondering what it the more optimal (in terms of memory, cpu usage, or any other criterious you know better than me) way to do ? :

*this kind of dynamical allocation

or

*a non dynamical allocation
(i mean :

TH1F myhisto(...)
)

(just in case : i do always the same plots and there variables
are always in the ntuple)

thanks !
