VAX 4000 Model 200 is  5 VUPs.
VAX 4000 Model 500 is 24 VUPs.

Do you mean SimH on the Mac is 3 times faster than your VAX?

That would put your MacBookPro SimH at 15 VUPs, and means that I would 
need a 3.8 Ghz processor to retire my VAX 4000 Model 500.

Of course the disk drives in use will also affect your compile speed.
