Intel Corp has run some Systems Performance Evaluation Co-operative system benchmarks of Unix System V.4.2 on a 50MHz 80486 processor, probably the first of their kind anywhere, and come up with some interesting results. They used the System Development and Multitasking suite, which is meant to reflect operating system efficiency together with input-output, processor, memory and cache. They found that with a 60-user concurrent workload, Destiny on the Intel chip was 28% faster than on a Digital Equipment Corp DECsystem-5900 and performed 87% as well as an IBM Corp RS/6000 970 running AIX. With a workload of 20 concurrent users, the system performed 88% as well as a Hewlett-Packard Co HP 9000 Series 700 Model 750. Intel says that the data indicates reduced overheads and streamlined input-output compared with Unix System V.4.2.
