The strength of friction is given in this setting.

Animation comparing Friction strengths of 10%, on the left, and 100%, on the right.
The Weight setting alters the influence each constraint type provides to the overall, global solution.
If you are only using one layer, this can be left at the default, 100%.
If you are combining different constraints in several layers, you could reduce this weight to lessen the effects of the connections and blend in other layers.
This parameter sets the limit on the number of connections each particle can make with other particles, when building a friction force.

In this animation, the Connection Limit is raised from 1 to 10.
