<div><p>To achieve the best performance, be sure to store your application
|
||
|
|
binaries in the local stream file system.</p>
|
||
|
|
<p>It is much slower to start <span class="keyword">i5/OS™</span> PASE
|
||
|
|
programs if your binaries (base program and libraries) are outside of the
|
||
|
|
local stream file system because file mapping cannot be done.</p>
|
||
|
|
<p>If you run an application in <span class="keyword">i5/OS</span> PASE
|
||
|
|
that performs a large number of fork() operations, it will not run as fast
|
||
|
|
as it runs on AIX<sup>®</sup>.
|
||
|
|
This is because each <span class="keyword">i5/OS</span> PASE
|
||
|
|
fork() operation starts a new <span class="keyword">i5/OS</span> job,
|
||
|
|
which can have a significant impact on performance.</p>
