Not an easy game...
My guess is
a) is about two times slower than b, c or d
b, c and d are about the same
difficult to say more without digging deeply into the code, but let's
other jts fan try...
Another guess is that differences may depends on the data itself !

Here is a skill testing question for the jts-devel list. I think all
of the following alternatives perform the same test .. what do you
think would perform faster?
a) return geometry.disjoint( geometry2 ) || geometry.touches( geometry2 )
b) IntersectionMatrix matrix = geometry.relate( geometry2 );
return matrix.isDisjoint() || matrix.isTouches();
c) return geometry.relate( geometry2, "F********" )
d) return !geometry.overlaps( geometry2 )
I will write a test harness for this; but the discussion may be
interesting.
