AIM TECHNOLOGY ANNOUNCES THE RESULTS OF THEIR UNIX OPERATING SYSTEM PERFORMANCE MEASUREMENT; Independent Performance Test Provider Publishes Objective Analysis to Help Companies Choose the Best PC-Based UNIX Operating System For Their Needs.SANTA CLARA Santa Clara, city, Cuba Santa Clara (sän`tä klä`rä), city (1994 est. pop. 217,000), capital of Villa Clara prov., central Cuba. , Calif.--(BUSINESS WIRE)--August 1, 1995--AIM Technology today announced the results of their Operating System operating system (OS) Software that controls the operation of a computer, directs the input and output of data, keeps track of files, and controls the processing of computer programs. (OS) Comparison, an objective performance analysis of two PC-based UNIX operating systems Noun 1. UNIX operating system - trademark for a powerful operating system UNIX, UNIX system operating system, OS - (computer science) software that controls the execution of computer programs and may provide various services , SCO OpenServer A server operating system for the Intel platform from SCO. It is based on Unix System V Release 3.2 and includes the Motif and X Window user interfaces and standard Unix networking (TCP/IP, NFS and NIS). SCO OpenServer has optional SMP support for up to 30 processors. Release 5 and Novell UnixWare 2. AIM's high-stress benchmark tests demonstrate system capability across a wide variety of user loads, from light to extremely heavy, resulting in a comparison of the two operating systems Operating systems can be categorized by technology, ownership, licensing, working state, usage, and by many other characteristics. In practice, many of these groupings may overlap. that serves to assist companies in making informed purchasing decisions. Novell's UnixWare 2 outperformed SCO's OpenServer Release 5 in both the file server test and the multiuser/shared system test. UnixWare 2 delivered 5 percent higher throughput under heavy loads over OpenServer Release 5 in the file server test and 9 percent higher peak performance and 10 percent higher sustained performance under heavy loads in the multiuser/shared system test. The results of the operating system comparison are: File Server Mix
UnixWare 2: peak performance 133.3 jobs/minute
sustained performance 103.5 jobs/minute/AIM load
OpenServer Release 5: peak performance 132.5 jobs/minute
sustained performance 98.3 jobs/minute/AIM load
Multiuser/Shared System Mix
UnixWare 2: peak performance 440.4 jobs/minute
sustained performance 421.6 jobs/minute/AIM load
OpenServer Release 5: peak performance 405.2 jobs/minute
sustained performance 383.5 jobs/minute/AIM load
"Under the load environments tested in this operating system comparison, Novell's UnixWare was the clear winner. However, performance test results will vary based on the load mix and environment used in the testing," said Jim Geers, president and CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. of AIM Technology. "The results of our operating system comparison indicate how important it is for our customers to model their specific environments and load mix to achieve performance test results that are tailored to their specific needs." Unlike many RISC-based systems A computer system that uses a RISC CPU such as a SPARC, PowerPC or MIPS chip. See RISC. , where there is normally only one version of a UNIX-based operating system available, the PC market offers a number of choices. AIM Technology benchmark tests demonstrate how system performance varies with the number of user loads. The results of the operating system comparison show how the relationships between performance and user loads can impact the choice of the "best" operating system for a specific application. For example, UnixWare 2 and OpenServer Release 5 offer the same levels of peak performance up to 25 user loads. From 25 user loads, their performance levels differ; however, they share the same peak performance level again at 50 user loads. When measuring the difference in completion times for concurrent jobs, UnixWare and OpenServer provide the same level of sustained performance up to 10 user loads. Over 10 user loads, sustained performance levels differ, but they converge again at 20 user loads. The operating systems were tested on the same hardware platform, the Compaq Proliant 4000, under AIM benchmarks Suite VII and IX using two application mixes, file server mix and multiuser/shared system mix. Under these two mixes, the operating systems were tested for peak performance -- the point of system throughput at which the most jobs can be processed, and sustained performance -- the size of the multitasking multitasking Mode of computer operation in which the computer works on multiple tasks at the same time. A task is a computer program (or part of a program) that can be run as a separate entity. load at which the system's performance could become unacceptable. Since 1981, AIM Technology has been providing vendors and end users with comprehensive performance testing Performance Testing covers a broad range of engineering or functional evaluations where a material, product, or system is not specified by detailed material or component specifications: Rather, emphasis is on the final measurable performance characteristics. . AIM's service helps users reduce the costs of evaluating new UNIX-based systems, and provides valuable broad-spectrum performance visibility for vendors that submit systems to be tested. AIM Technology is a privately held, performance testing organization for UNIX systems Noun 1.

The company also provides performance management tools for the UNIX systems market. -0- Editor's note Editor's Note (foaled in 1993 in Kentucky) is an American thoroughbred Stallion racehorse.
