   Possibly the lisp program for the Groebner basis computation is   
   uncompiled in your configuration.   
      
   The Groebner basis may also be run on the

   Yes, the time reported for the gcd is 0.0 seconds.   
      
   As I have said to the original poster, if there a computation that can   
   be done in two ways, and one of them is using a GB calculation,   
   you can expect that the other way is faster.
