Speed of tasks for different factions in The Settlers 2

In The Settlers 2, the different factions appear to have buildings that perform their core functions at different speeds compared to each others' equivalent. However, this difference in speed seems to be based off of the physical positioning of interactive areas on the buildings and how the settlers walk around it, as opposed to a simple timing variable, making measuring difficult.

What are the relative speeds of the various tasks between the factions? For example, do the factions take different amounts of time to saw boards into planks at a sawmill, or bake bread at a bakery, and if so, how much?
