  We compile a list of $14$ independent measurements of large-scale structure
growth rate between redshifts $0.067 \leq z \leq 0.8$ and use this to place
constraints on model parameters of constant and time-evolving
general-relativistic dark energy cosmologies. With the assumption that gravity
is well-modeled by general relativity, we discover that growth-rate data
provide restrictive cosmological parameter constraints. In combination with
type Ia supernova apparent magnitude versus redshift data and Hubble parameter
measurements, the growth rate data are consistent with the standard
spatially-flat $\Lambda$CDM model, as well as with mildly evolving dark energy
density cosmological models.
