Are very long acquisition times normal for 1H decoupled 19F solution states of NMR partiallly fluorinated organic molecules?

Running a 1H-decoupled 19F soln-state NMR experiment (1D) on 1,4 -difluorobenzene (0.1 ml in 0.5 ml CDCl3). It seems to require an extremely long acq. time. (truncating even at 8s acquisition...
