Not challenging the value-for-money of the above unit but recently I was 
curious how my seven-year-old, dual core, 2.7GHz i5 (macOS 12.0.1) 
compared to my 20+ year workhorse PWS500.

Digital Personal WorkStation with 1 CPU and 1536MB running VMS V8.4-2L1
Approximate System VUPs Rating : 159.0 ( min: 159.0 max: 159.0 )

innotek GmbH VirtualBox with 2 CPU and 3584MB running VMS V9.1-A
Approximate System VUPs Rating : 199.1 ( min: 195.8 max: 204.2 )

So moving to a (virtual) instance of VMS won't cost me anything 
performance-wise even if on this humble laptop.  BTW: running two 
concurrent VUPS.COM produces much the same result.

For comparison...

HP rx2660 (1.40GHz/6.0MB) with 4 CPU and 14335MB running VMS V8.4-2L1
INFO: Preventing endless loop (10$) on fast CPUs
Approximate System VUPs Rating : 495.1 ( min: 487.2 max: 499.6 )
