There is also the need for carrying out the performance evaluation of the most popular computers. The most popular computer today is the PC. There is a need felt for making an assessment of the operating system that is used in connection with the PC. Traditionally, the IBM PC operating systems, like Windows for Work Groups, Windows NT, and Net BSD, are actually considered. And there are three programmes that are used: WISH, which is a commander interpreter for tel language, HTTP Server and also Ghostview.
It is very interesting to find that Net BSD is giving the best to all the system functionality and in other cases the performance has varied by a factor of 2 to 7. The user may get struck with the Windows environment, but for access to the total system functionality you may have . based on the specific functionality for specific users such as office automation, scientific calculations, etc. we may need different environments.
In fact, similar performance evaluation can be carried out for large scale computing systems like DEC, Silicon Graphics Iris, Sun Solaris. All these things can be put to this kind of test.
