In this talk we present the results obtained from a study of O(2000) (quenched) lattice configurations from the APE collaboration, at 6.0≤β≤6.4, using both the Wilson and the SW-Clover fermion action. We determine the light hadronic spectrum and the meson decay constants. For the light-light systems we find an agreement with the experimental data of ∼5 for mesonic masses and ∼10 for baryonic masses and pseudoscalar decay constants; a larger deviation is present for the vector decay constants. For the heavy-light decay constants we find fDs=237±16MeV,fD=221±17MeV(fDs/fD=1.07(4)),fBs=205±35MeV,fB=180±32MeV(fBs/fB=1.14(8)), in good agreement with previous estimates.
