(Is anyone listening to me? ;) From "Amiga Unix Tech Notes" volume 1 number 1: X11R4, with your choice of window managers.

Is this reasonably close to being fact? From the Tech notes: An expanded and user selectable installation and configuration program.

The generic advice is: Unix + X11 requres 8 Megs. 2 megs of swapping sounds reasonable then. Especially since people (Dave Haynie I think) have said that on an Amiga Unix > 1 meg of chip memory is a waste since it only uses the 1, and that it is unavailable to the OS. > 7) I have also run a rough benchmarking program (that supposably computed >drystones per second) on the 3000UX/25, an 030 NeXT, and a DTK 80386/25 >running ESIX SysV R3.2.2.

Compiling the same source with the GNU >gcc compiler netted us a figure of over 6500. Much better ... gcc is a better compiler than AT&T's. gcc is PARTICULARLY good with 68000 family processors. From the Tech notes: new GCC-compiled kernel and utilities. Since gcc give twice the performance of AT&T's compiler (as you mentioned above) this should make the machine MUCH faster. To boot, X11R4 is much much much faster than R3. Remember, compiler differences are very important when comparing Dhrystones. -- <- David Herron, an MMDF & WIN/MHS guy, <- Formerly: David Herron -- NonResident E-Mail Hack <- <- "MS-DOS?
