|  The subject line says it all: what C compiler generates the fastest code?
|We just got Lightspeed C (v. 2.15), and someone in the group wrote a
|numerical integration program and said it ran on a Mac II at 1/4 the speed
|of an unloaded vax 11/750.

LSC 2.15 does not support direct access to the 68881.  It uses SANE which
uses the 68881, which of couse is much slower.  Version 3.0 is suppose to
support direct access the 68881, which will of couse speed up your program.

MPW 2.0 does support direct access to the 68881 and is also a true
optimizing compiler.  So while I've not done any performance numbers,
I supsect MPW will be the faster of the two for your application.
