• Is the CPU saturated? Consider upgrading the system, reducing the system workload, and tuning the system to reduce processing overhead.

• Is the memory over-committed? Consider upgrading memory, reducing system workload and tuning the system to reduce the memory working set.

• Is the communication adapter/communication controller too busy? Consider upgrading the network or pairing up token-ring cards.

• Is one of the subsystems too busy, and is this subsystem on the data path?

• Are any unnecessary processes or tasks running on the system? The general rule is not to configure or start services unless they are used regularly since they will waste system resources.

• Do a few processes or tasks use most of the resource? Can they be stopped? Can their priorities be reduced? Can they be refined so that they don't use as much resource?
