<h1 class="topictitle1">Set system benchmarks</h1>
|
|
<div><p>Setting good system benchmarks will give you performance data for
|
|
a properly tuned system. These performance benchmarks from both before and
|
|
after system changes provide important information for both troubleshooting
|
|
and planning.</p>
|
|
<p>You should establish system benchmarks before any major change in the system
|
|
configuration, for example adding a new interactive application or performing
|
|
a system upgrade. Maintaining accurate benchmark information can provide essential
|
|
troubleshooting information. At a minimum, benchmarks should include current
|
|
collection objects from Collection Services. Depending on your environment
|
|
you may need to maintain more detailed information using Performance Explorer.</p>
|
|
<p>Setting up a benchmark requires:</p>
|
|
<ul><li>That the correct <span class="keyword">iSeries™</span> configuration
|
|
is available</li>
|
|
<li>That the application and the data are representative and valid</li>
|
|
<li>That the correct version of all programs and software to be used are available</li>
|
|
<li>That the required number of users and workstations are available to run
|
|
the test</li>
|
|
<li>That the transactions are well defined for each user</li>
|
|
</ul>
|
|
<p>Running meaningful benchmarks for interactive workloads is almost impossible
|
|
without special equipment that allows you to simulate a user at a workstation.
|
|
To run a batch benchmark is, of course, not as complex a task as to test performance
|
|
of interactive applications, and the first three points above are still valid
|
|
for this type of test. However, setting system benchmarks on concurrent batch
|
|
and interactive work, which is frequently the actual customer environment,
|
|
also requires the appropriate number of users and workstations.</p>
|
|
<p>IBM<sup>®</sup> developed
|
|
a benchmark called the Three-in-One Benchmark to mirror the real-world demands
|
|
facing IT companies. The Three-In-One Benchmark clearly demonstrates that
|
|
the <span class="keyword">iSeries</span> server is an excellent
|
|
solution for today's small and medium businesses, which helps them run the
|
|
applications they need without worrying about performance.</p>
