Fixed joints (and sliders 'motorized' to be immobile) require math, and
math requires time.  If you got rid of those joints and just merged the
masses and geoms and used a single body, you'd gain some performance. 

If you have sufficient performance already... ship it.  :-)  The fixed
joint approach probably makes for simpler, cleaner, more maintainable
code, and there's something to be said for that as well.
