i redid my xwing fuselage and exported from spatch as a patch and now it
takes several minutes to render (parse is about 2 secs, pov file is
about 500k), where before i used two solid meshes and it took exactly 1
min to render (parse 11 secs, pov file miniscule, mesh incs 2.5 MB
each).  so what is up with that?  is there a way to just change the
patches?  but are patches cleaner looking?

Patches can do subdivision "on the fly", while rendering, to produce 
smoother results. Try the "type" keyword:
(from the manual)
"The keyword type  is followed by a float  Patch_Type  which currently 
must be either 0 or 1. For type 0 only the control points are retained 
within POV-Ray. This means that a minimal amount of memory is needed but 
POV-Ray will need to perform many extra calculations when trying to 
render the patch. Type 1 preprocesses the patch into many subpatches. 
This results in a significant speedup in rendering at the cost of 
memory."
