The "rate" property of gnlfilesource is READONLY. I am assuming you are
talking about the gnlfilesource element. You should be getting a
"GLib-GObject-WARNING" for this.

To actually change the rate you have to fiddle with the "duration" and
"media-duration" properties. So for a faster playback media-duration should
be greater than the duration and vice-versa for slow playback.

Also you have to use identity element to adjust the timestamps. E.G.: 
Below pipeline is for faster playback:
gst-launch gnlfilesource duration=10000000000000 
media-duration=100000000000000 location=file:///home/user/test.mp4 !
identity single-segment=true ! ffmpegcolorspace ! queue ! autovideosink
