u should not divide your mesh up that way.

but u should also not endup with more wrap nodes than the amount of wrap objects you have.

you have over 100!!! that is way too much for a basic humanoid character i assume.

each wrap akes time to calculate, and each subD deformation takes even longer.

if your mesh is not exceeding the verts limits of maya [which i highly doubt] then use a single mesh as the wrap object.

although, using multiple has "some advantages" over the control of deformation, but rigging it is actually much harder. more often a single mesh is just as good.
