<h4 id="rzajtper-anynetin">Performance considerations for AnyNet communications</h4>
|
||
|
|
<p>AnyNet® communications is a good performance factor for you to consider.
|
||
|
|
It is more expensive to use than any of the i5/OS™ protocols because you spend twice as
|
||
|
|
much to run two protocols.</p>
|
||
|
|
<p>To optimize AnyNet performance, consider the following:</p>
|
||
|
|
<ul>
|
||
|
|
<li>For send and receive pairs, the most efficient use of an interface is
|
||
|
|
with its own protocol stack. That is, intersystem communications function
|
||
|
|
(ICF) and common programming interface communications (CPI Communications)
|
||
|
|
perform the best with advanced program-to-program communications (APPC). There
|
||
|
|
is additional CPU time when the crossover between the protocols processes.</li>
|
||
|
|
<li>Each communications interface performs differently depending on the scenario.
|
||
|
|
ICF and CPI Communications perform the best with APPC.</li></ul>

<div class="notetitle" id="wq13">Note:</div>
|
||
|
|
<div class="notebody">An alternative to AnyNet communications is to have SNA and TCP/IP
|
||
|
|
running parallel or over the same lines in your network. Hence, performance
|
||
|
|
implications can be surpassed by not using AnyNet.</div>

<p>See <a href="rzajtrzajtcfg400toanynetpo.htm#rzajt-cfg400toanynet-po">AnyNet communications for the iSeries system</a> for the answer to the question:

What is AnyNet?</p>
