Jim, several things can make ejectors look sluggish. One is that the ejector exrtactor [is that the right term] can be worn or wobbly in the barrel letting the case rims slip by the ejectors a bit. Another is that the grease between ejectors is old and hardened and that area may need lubing. I have also seen the screw that retains the ejectors being just slightly too tight, but am not sure , on a Fox, if this is the "Fox" way. After lubing between the ejectors, try another type of shell and see if it acts the same.
