I found that TME's performance, with an Intel processor, and UltraSparc II  
processors that the ratio of host processor performance to emulated  processor 
performance is between 40 and 50 to 1.
So a 3.8Ghz Intel host, produces an emulated Sun3 running about 3800 / 50  = 
76 Mhz.  Or about twice as fast as the fastest Sun3(x), with a 33Mhz  68030 
So you can't go wrong getting the fastest Intel or AMD chip and running the  
emulator, but for ultimate NetBSD pkgsrc build performance, I would suggest  
using the MVME177 board and running NetBSD directly on it.  With a 60Mhz  68060 
and up to 256Mb memory, I think it might beat the emulator.   Wikipedia says 
that the 68060 has 2 to 3 times the performance of the 68040 at  the same 
clockrate.  So that would make it about 90Mhz equivalent.
