This helps to determine how well your system is performing and to spot potential problems before they happen. Developing a baseline will help determine how many users the system can support concurrently and the impact of running certain applications. It's a much better plan than waiting for your users to inform you of how slow the system is! It's also the first step in assuring that your system is running at optimum performance levels and that you have enough resources to support your environment. The second method of developing a baseline is to gather server resource statistics over time while the server is in use. The tests can be run at intervals over a period of weeks for a trend analysis. The results are documented and compared. Both methods can help you determine system throughput and where potential bottlenecks may be.
A set of programs encoded in ROM on IBM PC-compatible computers programs handle startup operations such as Power On Self Test (POST) and low-level control for hardware such as disk drives, keyboards, etc.
