I'm in the process of designing a compiler from a more conventional,
readable [ok, my opinion :-)] syntax into PostScript.  I would like
the code generated to be as efficient as possible and so find myself
in need of the following data:

  For any/all of the PostScript engines/interpreters out there, what
  are the relative speeds of the various operators, specifically:

    o Stack operators (dup,exch,roll,index,...) (and is there a point
      at which index and roll degrade due to argument size?)
    o Array/dictionary creation, reference, updating operators
    o Control operators (for,loop,if,ifelse)
    
  Also, what is the overhead for invoking a procedure? 

Thanks in advance, and I'll be sure to let y'all know if anything
comes of this.
