Performance Increases
Independent tests have shown that virtualised VAX solutions perform at many times the speed of original VAX hardware.
Performance Metrics: VUPs
When running on a 2.4GHz quad processor server with 1GB RAM, our virtualised solutions can achieve ratings of up to 500 VUPs (using SMP with 6 processors at up to 85 VUPs per processor).
This is over 3 times faster than a VAX 6660 (at around 150 VUPs) and around 13 times faster than a MicroVAX 3100 Model 96 (at 38 VUPs).
Example: Oracle Database Performance
The following results were taken from a trial by Oracle comparing a VAX 6650 with a virtualised solution running on a 2.4GHz quad processor server. On today's mid-range or high-end servers, the performance increases would be even greater.
