- I beg to differ about a Sun being faster than a 486DX2/66. Ofcourse, it
- depends on which sun... let us say a SPARC Station2 (~30 mips, according
- to Sun.)
-
- My experience has shown that a 486DX2/66, 8 MB RAM, running Linux .99
- is about 2x as fast as a Sparc2 with 16 MB RAM. (I have run a popular
- ray-tracer on both systems, and the Intel box was done doing the same
- trace in less than 1/2 the time.)
-
- So, I would suggest you get a pascal compiler for for Lunix, or shell
- out mega-bucks for a SPARC 10 with dual processors.
