 No, that's not realistic.  The most you can get is about 3% to 5%.  5%
with programs, wich do *much* arithmetic!

 Yes, that's the problem.  But one can get here in Germany a
patch-program for some money from a magazine called "c't", which reads
the built-in TOS and produces a new TOS (one has to burn it into EPROMS
of course) working with 68010/20.  I did this work with the TOS-1.2. 

 But some people are waiting for the release of a (not official)
TOS-version called KAOS-TOS, which is said to work with the 010/020/030
and bases on TOS 1.4.

 It's said, that it's compatible with ABC GEM 2.2, has no Line-F Code
and improvements an the AES and GEMDOS.

 One can even improve this program by using the KAOS-TOS together with
a new programm call NVDI (= new vdi).

 Results from Quick Index for KAOS and NVDI:

   TOS text:     286%
   TOS string   1075%
   TOS scroll    132%
   GEM dialog    367%

 (numbers from 'ST-Computer, 1/91, page 21)

 NVDI is a commercial program. 

 KAOS was offered to Atari, but Atari-US rejected it. (One can read in
our magazines, that Atari-Germany is very interested in this new
TOS-version.....)

 So the developers are still looking for another way to publish it. 
Some thought of the release via book, with a disk with a patch-program
on it........

 I thought, that the 040 is the first processor, which doesn't support
the variable bus-range (8-, 16- or 32-bit), which allows the 020 or 030
to work with a 16-bit architecture like the ST oder Amiga(500/2000).
