Do you think trench warfare sped up or slowed down the pace of war and why

Most definitely slowed down the pace of the war tremendously.

Explanation:

The nature of trench warfare made it almost impossible for either army to overtake the other. Attacking infantry was slowed down by the barbed wire and bombed-out terrain of No Man's Land, making the element of surprise unlikely. Later in the war, the Allies did succeed in breaking through German lines using the newly-invented tank.
