Are you saying that any completion in "M-x man" produces a lag?  If
so, there's nothing we can do here, except suggest that the OP
switches to a better OS.

The OP seemed to say that the lag happens only for some inputs
following "M-x man", in particular those which ends with a space.  Is
that not what you see?
