One large CAD package is "SPICE2G6" from U.C. Berkeley. It's a circuit
simulator. Here are measurements of a Sun3 and a Sun4, both running
SPICE2G6, ...
Using the SPEC versions of SPICE2G6 and EXPRESSO
Sun3/470 (top of the line sun3 cpu) 4761s 461s
Sun4/490 (top of the line sun4 cpu) 1486s 151s
Which is a factor of 3x.
Those with a serious interest in such things should examine the
results of commerical codes (which are often much faster, and have
been tuned for various platforms). The folks at HSPICE, for example,
would probably be happy to chat with you about your CAD needs.
