There is a correlation in the way a server is setup or configured and its performance.
Typically, while a newer and faster server could replace a slow one, it should be the last
effort in resolving the root cause of the performance issues. Poor server performance is
usually a symptom of poorly configured hardware, an improperly tuned operating system,
inefficient device drivers and applications, and/or slow clients.
The overall system performance can be greatly improved by using proper diagnostic tools
to pinpoint bottlenecks, and then eliminate them through proper configuration and tuning.
Typically, most bottlenecks in NetWare server environments are due to insufficient
memory. Adding more memory in such situations usually solves the problem. However,
there are other instances when considerable performance boost can only be achieved
through careful planning. Planning involves reconfiguration, operating system parameter
adjustments, device driver changes, and application modification to address platform
specific requirements.
For this section of the document, Ziff-Davis NetBench 7.0.2 (ent_dm_nb702.tst) was used
to simulate file and print I/O type requests in order to demonstrate the relative
performance characteristics of the ProLiant servers.
processor scalability simply means the capacity of a server to do more work at reasonable
response times as you increase the number of processors.
In order to quantify the processor-scaling effects of the ProLiant ML570 G2 server, use the
following commands to specify the number of processors to enable during a particular test
run:
Type stop processors 1 2 3 on the console command prompt to enable ONE
processor for the test.
Type stop processors 2 3 on the console command prompt to enable TWO
processors for the test.
Type stop processors 4 on the console command prompt to enable THREE
processors for the test.
Note: By default all four processors are enabled. Do not type the above commands to
enable all four processors for the test.
