I ran the same benchmark using our greenhills c-compiler and obtained about
1300/sec using 68020/cache/32bit memory/7.18Mhz clock.
The greenhills benches at about 850/sec on a plain 68000 amiga.

The V1.1 software automatically enables the cache on 68020 when booted.
I wrote the little cache enable program for CSA, but is not needed anymore
with 1.1.
