I have gotten the following using Lattice C 5.02 and Drystone benchmark

Compiling lc -v -w -cf -L -O -m0 -rr drystone using Amiga 2000 /68000 w/
expansion RAM : 
Registers - 1923 drystones/sec
No Regs - 1666 drystones/sec
I did a changetaskpri 100 before I ran it and had to modify the linker file
to also include lcs.lib since time() don't work with only lcsr.lib

Using the same compilation but -m2 and the A2620 board enabled I get

Registers - 5000 drystones/sec
No regs - 4166 drystones/sec

Some other benchmarks I got are (with A2620 enabled)

fib 52 secs
qsort 11 secs
savage (25000) 4 secs
100 sieves 5 secs
Whetstones - 769231 Whetstones/sec
