A-Shell Reference

Performance issues and optimization under A-Shell are not generally a concern, since A-Shell systems tend to exceed users' performance expectations. We don't take all the credit for this; it is mostly due to the overwhelming power of the hardware, and in the case of Unix, to the operating systems' sophisticated I/O logic. However, there are some cases, particularly those involving Windows networks, where a performance improvement would be highly desirable. And in any case, it is human nature to want anything to go faster. With that goal in mind, the following topics present several performance enhancement suggestions that are relatively easy to implement, as well as some explanations that may lead you to solve performance-related problems.
