How to speed up playback speed while editing ?

Hello all,

I am new DaVinci Resolve, I was wondering if it is possible speed up playback speed.

I have already tried to increase the playback frame rate but I had a lot of stuttering so I am looking for another method to speed up the playback speed.

What exactly do you want? Speeding up a clip for the final result or just play faster while viewing?
The latter is done by tapping the L key a few times (or J for playing backwards).
