SSL
6-2 Advanced Topologies for Enterprise Deployments
6.3 SSL
Remember that the use of SSL can add substantial performance overhead and use it
appropriately. The first request in an SSL session takes more longer than subsequent
requests. You should also understand how to configure session duration for SSL. See
the Oracle Application Server 10g Performance Guide and Oracle Application Server
Certificate Authority Administrator’s Guide for more information
6.4 Oracle Internet Directory (OID)
When using OID, use LDAP caching. you can also improve your performance with
jazn-xml if it is sufficient for your security requirements. See these guides for more
information;

6.5 JVM parameters
Set the appropriate Java Virtual Machine (JVM) parameters for your Java application
and your platform. Use the most recently certified JVM if possible. For example, JDK
1.4.1 is faster than JDK 1.3.1 in Oracle Corporation’s tests. See Oracle Application Server
10g Performance Guide for more information.
6.6 JSPs
You can improve JSP performance by disabling timestamp checking and disabling
session generation if they are not required.
6.7 Web Cache
Using of Web Cache can dramatically improve the performance of your application.
Evaluate your application for caching potential. Provide sufficient memory and
network bandwidth for Web Cache and use the fastest CPU possible. The increase in
throughput that is achievable with Web Cache can make network bandwidth the
primary bottleneck.
For more information, see Oracle Application Server Web Cache Administrator’s Guide.
6.8 Logging Level
By default, Oracle Application Server components have been set to logging levels
appropriate for a production system. More detailed logging can be enabled to provide
additional information, but will add performance overhead to your system. Reserve
the use of debug log levels for troubleshooting.
6.9 Database Connections
Several Oracle Application Server components provide database connectivity and
allow you to tune the number of database connections maintained and the duration of
database sessions. See Oracle Application Server 10g Performance Guide for more
