tips and tricks

Use the following tips to improve the disk subsystem performance. The processor utilization

parameters to check are:

• processor utilization – a server’s total processing capacity used during the last

second (listed as a percentage). Check the processor utilization regularly. If the

utilization is

> 90% over a sustained period of time, it probably indicates a processor bottleneck.

• watch for errant NetWare Loadable Modules (NLMs).

• make sure the current service processes counter is adequate.

• use Direct Access Memory (DMA) devices.

• upgrade or add another processor, if the processor is the bottleneck.

There are several tools available under NetWare for monitoring processor subsystem

performance and the general health of the server. Refer to the NetWare Performance

Monitoring Tools section of this document for more examples.

introducing

NetWare 6

ccordin

to Novell, the current version of NetWare 6 is a multithreaded, multitaskin

MP-enabled operating system. A thread is a stream of control that executes instructions

independently. This stream of instructions consists of tasks in the thread. A multithreaded

program is where two or more threads can execute concurrently. Typically, a

multithreaded program will not automatically run on more than one processor unless

specified by the code developer. A multithreaded operating system with multitasking

capability on the other hand can execute threads from different multithreaded programs
