  In this talk we present the results obtained from a study of ${\cal O}(2000)$
(quenched) lattice configurations from the APE collaboration, at
$6.0\le\beta\le 6.4$, 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 $\sim
5%$ for mesonic masses and $\sim 10%-15%$ 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 $f_{D_s}=237 \pm 16 MeV, f_{D} =
221 \pm 17 MeV (f_{D_s}/f_D=1.07(4)), f_{B_s} = 205 \pm 35 MeV, f_{B} = 180 \pm
32 MeV (f_{B_s}/f_B=1.14(8))$, in good agreement with previous estimates.
