I moved some code from AKCL on a Sun 3 to Allegro on an 030 NeXT. An informal timing test showed and 8 fold speed increase. Your mileage WILL vary. When I had a problem with Allegro's C interface, Franz Inc. debugged it in a couple of days. In addition, their upgrade policy has been _very_ affordable for me as an individual.
