Bottlenecks are not an uncommon problem. They occur when computer resources are stretched beyond there capacity, because of errant activities or because the workload is too great. To determine the which of the computers resources is the source of the bottleneck, investigation into these four general categories is advised.

The current Solaris behavior is that response of applications can suffer significantly when the file system is used heavily. On a workstation, this can be noticed as poor interactive response and trashing of the swap disk. On servers, the effect is degraded application response time, and low CPU utilization due to heavy paging.

The purpose of this paper is to introduce the performance analyst to some of the free tools available to monitor and manage performance on UNIX systems, and to provide a guideline on how to diagnose and fix performance problems in that environment. The paper is based on the author’s experiences with AIX and will cover many of the tools available on that and other UNIX platforms. It will also provide some Rules of Thumb for analyzing the performance of UNIX systems.
