Is anybody out there running Mathematica 3 on a Sun Ultra1/200e ?

I have been running Mathematica on an old PowerMac 7100/80 and I am
looking for a way to get more speed.  We have a Sun Ultra1/200e running
Solaris 2.5.1.  I am considering buying Mathematica for it but I would
like to get some idea of how much faster things will be.

I have checked Karl Unterkofler's Mathematica benchmak web page
<http://smc.vnet.net/mathkarl3.html> and see an entry for...

Machine: SUN Ultra 1, 200MHz, 196MB RAM  Version = Solaris 3.0 (November
22, 1996) Benchmark = 0.975

I ran the benchmark on my Mac and got...

Machine: PowerMac 7100/80, 104MB RAM, 105MB Virtual Version = Power
Macintosh 3.0 (May 6, 1997) Benchmark = 0.422

So it looks like the Sun will be only 2.3 times faster.  Can this be
right?  Our Sun has 384MB RAM, will that make a significant difference?

It looks like I could do much better by just adding an upgrade card to
my Mac...

Machine: Power Macintosh 7100/66, Newer MAXpowr G3 PDS, 88 MB, MacOS
7.5.5  Version = Power Macintosh 3.0 (October 5, 1996) Benchmark = 2.27


... 5.4 times faster!

Can somebody explain to me what is going on here?  Are the benchmarks
missleading?  Can someone running Mathematica 3 on a Sun Ultra1/200e
with a memory configuration closer to mine tell me about their
experience?  Could you run the benchmark for me & email me the result?

Thanks!
