We analyze the claimed tension between redshift space distorsions measurements of 
and the predictions of standard 
CDM (Planck 2015 and 2018) cosmology. We consider a dataset consisting of 17 data points extending up to redshift 
and corrected for the Alcock-Paczynski effect. Thus, calculating the evolution of the growth factor in a wCDM cosmology, we find that the tension for the best fit parameters w, 
and 
with respect to the Planck 2018 CDM parameters is below 
in all the marginalized confidence regions.
