Here's a vague idea of the simulation speed for a sample code
mix (these should be treated as peak numbers):

DEC VAX-11/780 4.3BSD			  8
Sun Sparc IPC SunOS 4.1.3		116
Motorola VME187 25Mhz 88100 SVR4	176
Sun Sparc 2 SunOS 4.1.3			203
IBM RS6000/950 AIX 2.3			313
Motorola VME197 50Mhz 88110 SVR4	529
