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.
A limit on the number of connections each particle can make.
Note: Too many connections can dramatically slowdown playback in the scene.

Animation to demonstrate a comparison of the Connection Limit value of 1, on the left, and 5, on the right.
This is the maximum distance to which surrounding particles are included in the viscosity solution.
