Actually this is not important at all. The real goal is to measure how much WORK can be done per second. This is also the goal of the DHRYSTONE test. The dhrystone test does NOT measure how many MIPS = million instructions per second your CPU does. If you think that this is what SYSINFO tries to calc, then you are wrong. The DHRYSTONE test runs a "defined workload" and compares the time taken - with how long a VAX computer need for it. And it knew how many Million Instruction that VAX did execute for this.So the MIPS printed in all these Dhrystone test is NOT the million instruction of your CPU - but how many MIPS a VAX would have needed to do this defined workload in the same time.
