Looks like you were using the native Lattice C compiler, as your Standard Amiga numbers are very close to the numbers Dale Luck (of CBM) posted awhile back. He also posted a Dhrystone number of 850 for the same code that was cross-compiled on a Sun using the Greehills compiler. Seems very apparent that one thing that's sorely needed for the Amiga is a *good* (read "well-optimized") compiler; it would seem that 850 is alot closer to the true capability of the Amiga, as that is in the same ballpark as the Dhrystones for the ST (the ST has been reported to run in excess of 1000 if the cursor is turned-off, etc). The 020 numbers ought to increase considerably with a good compiler, and could increase even more if it were optimized for the 020 chip itself; then with a "fast" 020 .... I leave it to your imagination! BTW, I have heard elsewhere that Aztec C will be ready for Beta testing in January ... /kim -- UUCP: {decvax,ucbvax,ihnp4}!decwrl!mips!kim DDD: 415-960-1200 USPS: MIPS Computer Systems Inc, 1330 Charleston Rd, Mt View, CA 94043
